Early Season Field Weeds

Spring wildflowers are the most prominent feature in our forests at this time of the year, while cold-season weeds are most prominent in the vegetable fields. If you want to see images of the spring wildflowers in the forests of Hawthorne Valley, please go into the archive and find the blog we posted on April 30, 2011.

Today, I am going to share the results of a little inventory of early season weeds found during the last two weeks in the vegetable fields at Hawthorne Valley Farm. (Be assured, the farmers have been very busy discouraging the weeds from completely taking over and replacing them with neat rows of vegetable seedlings…)

Probably the most common and ubiquitous weed of early spring is Common Chickweed (Stellaria media). It is originally from Europe, but now found on all continents, including Antarctica. It was documented in New England as early as 1672. Common Chickweed is very hardy and often stays green under the snow. Its trailing stems can be several feet long. It grows very quickly and is capable of producing seeds five weeks after germination. No wonder, that certain garden beds are all but covered in it!

CARYO Chickweed (Stellaria media) 7931

Common Chickweed is a member of the Pink Family (Caryophyllaceae) and is characterized by small opposite leaves with a pointed tip. The flowers are composed of five deeply cleft petals.

CARYO Chickweed (Stellaria media) 7904

Tender leaves of Common Chickweed can supposedly be eaten raw as an addition to salads or boiled and served as greens. A tea of this herb is traditionally used to relieve coughs and externally for skin diseases and to allay itching. An infusion of Chickweed is also an ingredient in a skin healing salve prepared here in Columbia County on Red Oak Farm.

A close relative is the introduced Mouse-Eared Chickweed (Cerastium fontanum ssp. vulgare). It too has small opposite leaves, but they are hairy and their tip is more rounded.

CARYO Mouse-Eared Chickweed (Cerastium fontanum spp. vulgare) 7902

There are several other early season weeds in the Pink Family, all recognizable by their opposite leaves. My current assessment is that they are the introduced Bladder Campion (Silene vulgaris = S. cucubalus), White Campion (Silene latifolia = Lychnis alba), and Ragged-Robin (Lychnis flos-cuculi).

The following weed, which I tentatively identified as Bladder Campion (Silene vulgaris), has very regularly-spaced, extremely smooth, opposite leaves.

CARYO Bladder Campion (Silene vulgaris) 8007

The weed below, tentatively identified as White Campion (Silene latifolia), has much larger, slightly hairy leaves that emerge closely spaced, almost creating a rosette.

CARYO White Campion (Silene latifolia)

Finally, these very narrow, smooth, and opposite leaves likely belong to Ragged-Robin (Lychnis flos-cuculi).

CARYOPH Ragged Robin (Lychnis flos-cuculi) 8019

This sums up the prominent opposite-leaved weeds of early spring.

The next group are the weedy members of the Mustard Family (Brassicaceae), which also happens to include many of our cultivated plants, such as Arugala, Broccoli, Cauliflower, Brussel Sprouts, Kohlrabi, Cabbage, and Kale. Many of these weeds start the season as basal rosettes.

Currently the most prominent in the fields around here is Shepherd’s Purse (Capsella bursa-pastoris). This weed comes from southern Europe and was reported in North America prior to 1672. Its basal rosette is slightly reminiscent of Dandelion, but its leaves are more deeply divided and the leaflets of interesting, irregular shapes (and extremely variable from plant to plant). A broken-off leaf does not exude white milk (as it would in Dandelion or Chicory) and, upon closer inspection (hand lens!), Shepherd’s Purse has branched hairs to help with its identification. Sometimes, these plants can’t wait to flower and instead of growing a proper flowering shoot, they produce a few flowers in the center of the rosette.

BRASSICA Shepherd's Purse (Capsella bursa-pastoris) 7943

Some rosettes have less divided leaves…

BRASSICA Field Pepperweed (Lepidium campestre) 7984

… some more. But like many early season weeds, Shepherd’s Purse always has a long taproot.

BRASSICA Shepherd's Purse (Capsella bursa-pastoris) 7939

Below is a typical example of a flowering Shepherd’s Purse. The flowering shoot emerges from the center of the rosette and bears only slightly divided or toothed leaves. The flowers are tiny, white and have four petals, like all members of the Mustard Family.

BRASSICA Shepherd's Purse (Capsella bursa-pastoris) 7936

The young leaves (gathered before the flowers appear) of Shepherd’s Purse can reportedly be used in salads or prepared like spinach. Dried seedpods make a pepperlike seasoning. Traditionally used as a diuretic, to stop bleeding, and during childbirth for its uterine-contracting properties.

Field Penny-Cress (Thlaspi arvense) is another very common early season weed in most vegetable fields at Hawthorne Valley Farm. It originates in the eastern Mediterranean region and was first reported on this continent from Detroit in 1701. As one apprentice observed, it almost looks like Corn Mash. It is considered an edible plant for salads, cooked greens, and seasoning. But it also bears the name “Stinkweed” and supposedly gives meat and milk an unpleasant flavor if animals consume a lot of it.

BRASSICA Field Penny-Cress (Thlaspi arvense) 7901

When Field Penny-Cress is getting ready to flower, its axis begins to elongate, just like in a bolting lettuce and most other rosette forming plants.

BRASSICA Field Penny-Cress 2 (Thlaspi arvense) 7922

An intense peppery taste identifies the following weed as Field Pepperweed (Lepidium campestre). Although it is considered edible, just like its cousins mentioned above, it is a bit strong for my taste. Its leaves are not as deeply divided and as closely hugging the ground as those of Shepherd’s Purse, but they are also not as smooth-margined and organized-looking as those of Field Penny-Cress…

BRASSICA Field Pepperweed (Lepidium campestre) 8016

The following weed, which looks like a hairy Dandelion, is actually also a member of the Mustard Family, most likely a Hedgemustard (Sisymbrium officinale).

BRASSICA prob. Hairy-Pod Hedgemustard (Sisymbrium officinale) 8025

Continuing with variations on the theme of basal rosette, these smooth and very round-lobed leaves belong to Wintercress (Barbarea vulgaris). This is another species that basically stays green below the snow. The young leaves are supposedly excellent when picked while the nights are still frosty and can be added to salads or cooked like spinach. With warmer weather, the leaves become very bitter, but the tight clusters of flowerbuds can then be boiled and served like broccoli.

BRASSICA Wintercress 2 (Barbarea vulgaris) 7925

Finally, here is a mustard weed that somewhat breaks the basal rosette stereotype. Its young plants are upright and its leaves entire. However, the branched hairs (a character it shares with the otherwise very different-looking Shepherd’s Purse) make me believe we are looking at Wormseed Mustard (Erysimum cheiranthoides).

BRASSICA Wormseed Mustard (Erysimum cheiranthoides) 8029

Change of gears: let’s look at a couple of weeds with roundish, opposite leaves. Their square stems (amongst many other characteristics) place them in the Mint Family. The first one is Ground Ivy (Glechoma hederacea), a very common weed of lawns, pastures, and obviously also fields. It is a creeping plant which roots at the nodes. Its opposite leaves are born on long stalks. Crushed leaves are aromatic, medicinally-smelling. Traditionally, a leaf tea was used for lung and kidney ailments and as “blood purifier”. Externally, it is a folk remedy for cancer, backaches, bruises, and hemorrhoids. Supposedly, the dried leaves make a fine herbal tea when steeped for 5-10 minutes in hot water.

LAMIA Ground Ivy (Glechoma hederacea) 7907

The other weed species is quite similar and also belongs to the Mint Family. But its shoots are more upright, not rooting at the nodes. Its opposite leaves are stalked in the lower parts of the plant but in the upper part they are sessile, attached directly to the main shoot. This identifies it as the much less common (in our region) Henbit (Lamium amplexicaulum).

LAMIA Henbit (Lamium amplexicaulum) 7923

Ground Ivy flowers are bluish-purple, while Henbit flowers are pink.

LAMIA Henbit (Lamium amplexicaulum) 7924

Another pretty early flower is produced by Bird-Eye Speedwell (Veronica persica), a member of the closely Snapdragon Family (Scrophulariaceae). Its toothed leaves are opposite along the base of the shoot, but near the flowers they become alternate.

SCROPH Bird-Eye Speedwell (Veronica persica) 7955

The sky blue flowers with their prominent dark blue “landing strips” that guide bees to the nectar, are presented on relatively long stalks.

SPROPH Bird-Eye Speedwell (Veronica persica) 7952

The Corn Speedwell (Veronica arvensis) looks very similar, but tends to have smaller leaves and its tiny blue flowers have no or only very short stalks.

SCROPH Corn Speedwell (Veronica arvensis) 8017

We will close with a few “oddballs”. Here are the three-foliate, Strawberry-like leaves of Rough Cinquefoil (Potentilla norvegica), a member of the Rose Family (Rosaceae) that will soon be producing little yellow flowers. Rough Cinquefoil is considered native to this continent and one of the few native plants that readily associate with cultivated soil.

ROSA Rough Cinquefoil (Potentilla norvegica) 8009

Somewhat similar in appearance are the palmate (“hand-like”) leaves of a member in the Geranium Family, possibly Carolina Geranium (Geranium carolinianum).

GERANIA possibl. Caronlina Geranium (Geranium carolinianum) 8012

Finally, there is a little violet, aptly named Field Violet (Viola arvensis) that can become very prevalent in some vegetable fields. It has toothed, long-stalked leaves of variable shape …

VIOLA Field Violet (Viola arvensis) 7911

and flowers very early in the season.

VIOLA Field Violet (Viola arvensis) 7949

The information about the date when an introduced weed species was first documented on this continent was gleaned from “Weeds of Canada and the Northern United States” by France Royer & Richard Dickinson. I consulted the Peterson Field Guides on “Edible Wild Plants” by Lee Allen Peterson and “Eastern/Central Medicinal Plants” by Steven Foster and James Duke about culinary and medicinal uses of the weeds. Weed identification was facilitated by “Weeds of the Northeast” by Richard H. Uva, Joseph C. Neal and Joseph M. DiTomaso, and the “Manual of Vascular Plants of Northeastern United States and Adjacent Canada” by Gleason & Cronquist.

As I indicated in the text, some of the identifications are tentative, because they are based on sterile specimens. Please do let me know if you detect any obvious errors in my best guesses. Thanks!

Encouraging Fall Flowers and their Insect Visitors on Farms in the Hudson Valley

Flowers are beautiful. Flowers are also necessary to produce many fruits and vegetables we like to eat. For example, there are no tomatoes without tomato flowers and no cherries without cherry blossoms. Additionally, flowers are a crucial resource for many insects, some of which, in turn, are beneficial for agricultural production.

In this blog, we want to share some late season images (most of them taken in late September/early October 2017) from the Hudson Valley, which illustrate different approaches to enhancing flower abundance on farms. While some of these approaches were the result of deliberate management to invite more flowers and beneficial insects onto the farms, others were more incidental. The photos were taken by various members of our team (see photo credits at the bottom) as part of a multi-farm study to compare the distribution of flowers and insects in vegetable fields and surrounding semi-natural areas. The pictures are from Hawthorne Valley Farm, the Hudson Valley Farm Hub, Ironwood Farm, and Hearty Roots Community Farm.

Hawthorne Valley Farm – Creekhouse Garden

Increased on-farm flowers through adjacent residential landscaping

Our program occupies one of the buildings on the farm, adjacent to a pasture. Since 2010, we have worked slowly, but steadily, to invite more species of native plants into the 1/2 acre yard around the house. The early years of that effort are described on the Hawthorne Valley Farmscape Ecology Program website.

This fall, the rain garden (where we collect the runoff from the parking lot), sported a mix of planted and volunteer native plants, such as New England Aster, Purple-stem Aster, Panicled Aster, Canada and Rough-leaved Goldenrod, Brown-eyed Susan, Obedience Plant, Indian Grass, and Big Bluestem.

View from the rain garden at the Creekhouse towards the barns of Hawthorne Valley Farm (photo by CKV).

The dryer roadside garden has several of the same species (they usually don’t grow as tall, there) in addition to Narrow-leaved Mountain Mint and Wild Bergamot.

In the shadier areas, Heart-leaved Aster displays a last hurrah of summer with its dense lavender-colored flowers.

Much of the former lawn has slowly been transformed into a native wildflower meadow, where New England Aster and Showy Goldenrod put on a spectacular show of colors in late September.

New England Aster and Showy Goldenrod both propagate readily from seeds collected in the fall and stored in a dry cool place over the winter (photo by CKV).

Migrating Monarch butterflies, of which there were a lot more this year as compared to the last few years, were thankful for the nectar!

But not only the showy butterflies graced the garden with their presence. Honey bees were busily collecting nectar on the different aster and goldenrod species…

… as did the native bumblebees.

A Common Eastern Bumblebee is approaching the flower heads of Panicled Aster (photo by CRV).

The less conspicuous small wasps where everywhere. Many of these smaller cousins of the dreaded Yellow Jackets are important beneficial insects for the farmer. Most of them are parasitoids, which lay their eggs into the larvae of other insects and thereby contribute to the biocontrol of pests.

A probably parasitic small wasp (photo by CRV).

Another group of beneficial insects are the hoverflies. Other than bees and wasps, which they often resemble because of their yellow and black markings, these flies do not sting. The larvae of many species are ferocious predators of other insects and also contribute to biocontrol of pests. The adults feed on nectar and pollen, and serve as pollinators. Here are images of three different species of hoverflies found on asters in the Creekhouse Garden.

Most likely, this hoverfly is Syrphus torvus, a common species whose larvae feed on aphids. This adult is visiting the flower heads of Heart-leaved Aster (photo by CRV).

Toxomerus germinatus, another species of hoverfly, visiting the flower heads of Panicled Aster (photo by CRV).

However, not all flower visitors were interested in collecting pollen or nectar, or functioning as pollinators. This katydid was happily munching away on the white petals (ray flowers) of a Calico Aster.

Another creature was not interested in the flowers per se, but had set up shop to try and catch one of the abundant flower visitors.

Hawthorne Valley Farm – Hedgerows

Increased flowers by letting natural diversity bloom

Hawthorne Valley Farm has an abundance of hedgerows which separate the various pastures and fields. In the Spring, most flowers in this habitat are borne on the native (and non-native) shrubs that compose the backbone of these hedgerows. Late in the season, asters and goldenrods thrive along the unmowed edges of the hedgerows. Such “soft edges” between different habitat types or landscape features might appear ungroomed, but are very important for insect life. Unmowed riparian corridors and infrequently mowed wetlands can serve a similar purpose.

Ironwood Farm – Old Fields Surrounding the Intensively Managed Fields

Increased flowers by allowing some former farmland to remain fallow

Ironwood Farm is a young farm reclaiming former farmland. Currently, the intensively managed vegetable fields are surrounded by old fields that have developed into perennial meadows, composed of varying mixes of native and non-native plants. We have observed an exceptional abundance of native bees in the vegetable fields of this farm and suspect that the surrounding old fields and their flowers may help support these bees, which then serve as pollinators in the vegetables. In addition, the Common Milkweed plants (note the large, oval leaves in the center of the image below) in the old field served as food plants for Monarch butterfly caterpillars, making Ironwood Farm a nursery as well as a stop-over for migrating Monarchs.

A goldenrod and aster dominated old field just outside the deer fence of the vegetable field at Ironwood Farm might contribute to the abundance of native bees we observed in the vegetables (photo by CKV).

In the fall, the flowers of New England Aster contrast beautifully with those of Canada Goldenrod in the old field (photo by CKV).

Earlier in the season, the old fields had many flowers of non-native plants, such as Knapweed, which nonetheless were very attractive to native pollinators.

Hawthorne Valley Farm – Corner Garden Cropland

Increased flowers through interspersed in-bed annuals

The Corner Garden near the school parking lot is a small, intensively managed vegetable field. The farmers are experimenting with augmenting the abundance of flowers near the vegetables by interplanting annual wildflowers (such as the pink Cosmos pictured below) within the vegetable beds. While some vegetables, such as tomatoes, peppers, eggplants, cucumbers, zucchini, and squash have to flower before producing the vegetable we eat, others, such as lettuce, carrots, parsnips, chard, beets, fennel, kale, broccoli, cabbage, cauliflower, and kohlrabi don’t get to flower before they are harvested. Occasionally, when feasible within the crop rotation, left-over crops (such as the Fennel pictured below) are allowed to bolt and flower, adding to the abundance and variety of flowers in the garden.

Late season flowers in the Corner Garden are provided by a Cosmos plant which was interplanted with Fennel and the Fennel itself, which is allowed to bloom before the bed is seeded with a cover crop for the winter (photo by CKV).

Hawthorne Valley Farm – Corner Garden Borders

Increased flowers through perennial edge plantings

In addition, we have collaborated with the farmers to bring more flowers into the Corner Garden by establishing small plantings of woody and perennial native plants around the perimeter of the vegetable beds. On the right in the image below is an area that was planted in early summer (with the help of several volunteers) with New England Aster, Showy Goldenrod, Wild Bergamot, Narrow-leaved Mountain Mint, Butterfly Milkweed and Swamp Milkweed, all propagated from seeds collected at the Creekhouse Garden, in addition to some Yarrow and Lemon Balm plants. The abundant flowers of New England Aster (patch of purple flowers in image) became a true insect magnet in the fall, feeding migrating Monarch and Painted Lady butterflies, the Honeybees from the nearby hives, a plethora of native bees, hoverflies, and other beneficials, as well as the not-so-beneficial Cabbage White butterflies.

This planting was recently expanded (again with the help of several tireless volunteers) to incorporate a number of additional native wildflowers grown from seeds by volunteer Betsy Goodman-Smith. The perennial patch now also contains Purple Coneflower, Black- and Brown-eyed Susan, Anise Hyssop, Lance-leaved Coreopsis, Mistflower, Cardinalflower, Partridge Pea, Slender Lespedeza, and Purple Prairie Clover (the seeds for most of these species were donated by the Hudson Valley Farm Hub). We are looking forward to this wildflower patch providing nectar and pollen for insects all through the season, next year…

Hudson Valley Farm Hub – Vegetable Fields

Increased flowers through bed-scale annual insectaries

In the large vegetable fields at the Farm Hub, the farmers experimented with several annual insectary plantings. The image below shows a section of the garden that had been seeded with Prairie Coreopsis in spring and was allowed to flower for a second time to provide late-season floral resources for insects.

An insectary strip of annual Plains Coreopsis integrated in the vegetable fields at the Hudson Valley Farm Hub (photo by CKV).

The Coreopsis insectary became a lunch stop for migrating Monarch butterflies. We estimate that at least 50 Monarchs were nectaring in this patch at a time.

However, the Monarchs were not the only migratory butterflies who stopped to fuel up on energy-rich nectar. Painted Lady butterflies on their way to Texas and Northern Mexico were even more common than the Monarchs on the Coreopsis flowers.

Other visitors to the Coreopsis flowers in the insectary planting included Sulphur butterflies, hover flies, and Honey Bees (all pictured below).

A variety of insects, other than the migratory butterflies, visited the Coreopsis flowers (clockwise from top left): Sulphur butterfly, hover fly (most likely Syrphus torvus), and Honey Bee (photos by DAC).


Hudson Valley Farm Hub – Test Plots

Increased flowers through field-scale planting of perennial native meadows

This spring, we established 4.5 acres of native meadow trial areas in flood-prone fields at the Hudson Valley Farm Hub. We are experimenting with two seed mixes (Mix A and Mix B; see below) to compare their success in establishing meadows without the use of herbicides on former corn fields. We also monitor their suitability for erosion control, soil building, and as insect and wildlife habitat. We received invaluable technical support on this project from the Xerces Society, who is collaborating with the USDA/NRCS throughout the US to help make farms more pollinator-friendly.

Mix A is rich in wildflowers and might, eventually, be most attractive to pollinators and other beneficial insects. It is also quite expensive.

Mix B is rich in native grasses with some wildflowers added. It is more economical and might, eventually, lead to meadows that attract grassland breeding birds as well as a decent amount of beneficial insects.

By early October, some of the test plots are well on their way to dense and diverse native meadows. The vegetation is relatively low because the test plots had been mowed throughout the summer to discourage the annual weeds.

A closer look into this patch of meadow (seeded with Seed Mix A) reveals a mix of blossoms from Mistflower (light blue), Black-eyed Susan (yellow), and Blanketflower (red). The seedlings of about 20 additional native plant species are well established and have spent their first season developing a strong root system. They are expected to begin flowering next year. The seeds of a few species remained dormant for the first season and are expected to germinate next spring.

A closer look at the late season flowers in the native meadow trial (photo by CKV).

Bees, wasps, hover flies, moths, and butterflies, including Monarch and Painted Lady, were visiting the flowers in these meadows, but in smaller numbers compared to the Coreopsis insectary, which had a much higher flower density.

Two very different species of hover flies: Drone Fly on Blanketflower (left) and Helophilus fasciatus on Black-eyed Susan (right) (photos by JM).

The Sulphur butterfly is one of the most ubiquitous butterflies on farms. Its larvae feed on clovers and alfalfa, and adults can be found nectaring on a large variety of flowers.

An exciting observation was the Milbert’s Tortoiseshell butterfly visiting flowers in the native meadow trial. This is a northern species which, in some years, shows up in our region. This is our first sighting of this species in the Hudson Valley in more than a decade.

Hudson Valley Farm Hub – Medicinal Herb Garden

Increased flowers through blossoming herb crops

One of the farmers in training at the Farm Hub chose to experiment with the growing of medicinal herbs, this season. By mid summer, her herb garden was buzzing with bees and hopping with butterflies. The herbs were harvested by the time we took our last round of photos, so here are a couple of images from the herb garden in July.

The medicinal herb garden in July. In full bloom at this time were Toothache Plant (yellow), Calendula (orange), and Blue Vervain (purple) (photo by CKV).

It was particularly impressive, to see the Blue Vervain, a native plant of wet meadows, in a dense bed of obviously very happy plants in full bloom. The insects were all over them in July!

Hearty Roots Community Farm – U-Pick Flower Beds

Increased flowers through bee- and butterfly-friendly cut-flower beds

Another type of flower found on several farms this fall were ornamental plants grown for cut flowers. While ornamental flowers often originate from other parts of the world (e.g., Calendula comes from Southern Europe and Strawflower from Australia) and horticultural varieties bred to please the human eye often don’t provide much (if any) nectar and/or pollen for insects, we were happy to observe during our flower watches in the cut-flower beds of Hearty Roots Community Farm, that some species were very popular with the insects.

One of them was Zinnia, an easily grown annual which is represented in many flower gardens and a staple in cut flower arrangements. It is native to the Southwestern US and into South America.

A bed of Zinnia in the cut flower garden at Hearty Roots Community Farm (photo by CKV).

The Monarchs and Painted Ladies might “know” this plant from Mexico and seem to LOVE it! (Of course, the individual butterflies we observed here this fall have not yet been in Mexico, so their “knowledge” of Zinnia–if any–would be at the level of the species which have co-evolved with the nectar plants.)

Monarch butterfly on Zinnia (photo by DAC).

Globe Amaranth is also often a component of locally grown flower bouquets, but its natural distribution is even more tropical than that of Zinnia, from Central into South America. Its flower heads are reminiscent of clover and seem to be very attractive to a variety of butterflies.

A bed of Globe Amaranth in the ornamental flower garden at Hearty Roots Community Farm (photo by CKV).

It was visited by some butterflies that are common resident species of our area farms, such as the Sulphur and Gray Hairstreak.

However, we also observed several butterfly species on the Globe Amaranth, which are resident in the southern US and only sometimes stray as far north as our region. These include the Fiery Skipper, Common Checkered Skipper, and Common Buckeye.

Fortunately, there are many possibilities to enhance flower abundance and insect life on farms (and in your gardens!), whether it involves adjusting the mowing schedule of natural areas/field edges/surrounding old fields so that the wildflowers can blossom; allowing certain vegetables to bolt and bloom; planting flowering medicinal herbs or pollinator-friendly cut flowers; interplanting annual flowers with vegetables, either as individual plants, or in insectary strips; using flowering cover crops; or establishing perennial wildflower areas at the field or nook & cranny scale. Each of these approaches can help make the farmscape more diverse and alive. They vary in their scale and in the time and money investment they require, so think about what’s the best fit for your situation. Where there are suitable flowers, the pollinators and other beneficial insects will be rewarding you with their beauty and service.

We thank the farmers at Hawthorne Valley Farm and the Hudson Valley Farm Hub for their collaboration with the experimental establishment of native wildflowers. We also thank them, and the farmers at Hearty Roots Community Farm and Ironwood Farm for tolerating our research for the multi-farm comparison of the distribution of insects across on-farm habitats.

Gardening with native plants

As some of you might know, we have begun two years ago to landscape with native plants around the Creekhouse in Harlemville. We had been motivated to do this by the beauty of the native plants we have gotten to know during our inventories in their wild habitats, by witnessing the ecological impact of invasive plants that have escaped from ornamental gardens, and also by books like “Bringing Nature Home” (Doug Tallamy, 2007) and “Noah’s Garden: Restoring the ecology of our own backyards” (Sara Stein, 1993).

We thought, we were part of a rather new “gardening with native plants”  movement.

However, last week, I realized how old this tradition of gardening with natives really is. Conrad gave me a copy of the book “American Plants for American Gardens” by Edith A. Roberts, Professor of Botany at Vassar College, and Elsa Rehmann, Landscape Architect. It had been published in 1929!!!

In this blog, I will share with you some images of native plants we have invited into the landscape around the Creekhouse. Some of these native plants grow in traditional garden beds that were started “from scratch” either by smothering existing vegetation with newspapers and mulch (e.g., the Roadside Garden and the Shade Garden) or by digging holes and then filling them with topsoil brought in from other places on the farm (e.g., the Rain Garden and the Welcome Garden). Other native plants continue to grow right where we found them and we are slowly working on giving them more and more space by removing non-native competitors (e.g., the South and West Slope). Finally, there are areas currently largely dominated by non-native plants, where we have begun to introduce native plants by transplanting or seeding (e.g., the Orchard Meadow, the Fence Line, and the Seep). If you would like to see pictures from the very beginning of the Creekhouse Garden, please go back to the blog from 21 July 2011.

You will see, we try to be relatively strict in our definition of “native”. We mostly (although not exclusively) invite plants into the garden that are considered native to NY State and have a long history of growing wild in Columbia County (see “Flora of the Columbia County Area, New York” (McVaugh, 1958) and our draft of an updated plant list for Columbia County).

I should also say that we NEVER transplant plants from the wild into the garden. Many of our native plants are not common in the wild and there is always a large risk that a transplant does not survive. Native plant gardens should supplement, not diminish the wild populations! We do collect seeds from wild-growing plants and try to grow our own seedlings (which has worked really well with some species and not at all with others…) and we accept transplants from gardens of other native plant enthusiasts.

The most visible of our garden areas is the Roadside Garden:

The Brown-eyed Susan (Rudbeckia triloba) which brings a lot of yellow to the Roadside Garden had been lingering among the “weeds” in the original overgrown garden bed and was one of the few species we did not smother with newspaper. These plants have thanked us with a spectacular come-back and we are happy to have their cheerful color, although nobody knows for sure whether they should be considered truly native to the County. The tall pink-flowered Joe-Pye-Weed (Eupatorium maculatum) has been planted from a potted plant purchased from Project Native two years ago. The orange Turk’s-Cap Lilies (Lilium superbum) are strictly native only to Long Island and a set of counties along the southern border of NY State. But they were given to us by our neighbor John Piwowarski and we love to have them!

Further along the road, the Brown-Eyed Susans are joined by the purple Showy Tick-trefoil (Desmodium canadense) which we grew from seeds collected two years ago from the bank of Route 22, just south of its junction with Route 5 in Austerlitz (this is so far the only wild patch of this species we know). The blue mist in the background are the flowers of Downy Skullcap (Scutellaria incana), a species so rare that it is listed as endangered in NY State. It has not yet been found in Columbia County and the plants in our garden were propagated by Project Native.

A close-up of Showy Ticktrefoil reveals it as a member of the legume family with pea-shaped flowers and tri-foliate leaves. It’s pods are “stickers”, equipped with a hairy surface that is designed to make the seeds hitchhike in animal’s fur. So, watch out when weeding near a Ticktrefoil, else you might end up with seedpods in your hair and on your clothes…

A few plants of Slender Mountain Mint (Pycnanthemum tenuifolium) are still in full bloom in the Roadside Garden. The closeup image below reveals the delicate shape and coloration of each of the tiny individual flowers.

These Mountain Mints were transplanted from another garden, but we do find this species regularly thriving in old fields, often together with Bee Balm (Monarda fistulosa).

Bee Balm was in bloom all through July in our garden and had some awesome visitors…

… such as this Hummingbird Clearwing Moth (probably Hemaris thysbe).

The west end of the Roadside Garden is defined by Wild Senna (Senna hebecarpa), growing happily from stem cuttings taken from plants in Ruth Dufault’s garden. Wild Senna naturally grows in Columbia County along the Hudson River near tidewater but does not mind a spot in a garden bed, either…

Here and there, throughout the Roadside Garden, one can find clumps of native grasses, such as Little Bluestem (Schizachyrium scoparium), Big Bluestem (Andropogon gerardii), and Purpletop (Tridens flavus).

Closeup of the dangling stamens (yellow) and the feathery stigmas (deep purple) of Big Bluestem. Who said that grasses don’t have flowers? They might not have showy petals, but everything else that is needed to produce seeds is there!

Earlier in the summer, the Roadside Garden was dominated by a big patch of white flowers from Beardtongue (Penstemon digitalis). Several of these plants were barely “hanging in there” amongst the non-native grasses and weeds along the roadside when we first began to shape the garden. We have saved and transplanted several of them and they have recovered spectacularly! In the foreground, you see two Showy Goldenrod (Solidago speciosa) plants with their broad leaves and reddish stems. This is a rare species of goldenrod which does not spread as aggressively as the common Canada Goldenrod (Solidago altissima). The clump of grass on the right is Purpletop (Tridens flavus), a warm-season grass that is slow getting started in the spring but produces beautifully delicate purplish inflorescenses in late summer. This grass was grown from seed collected from a road-side population by our landscaper friend Wendy Carroll.

Finally, a spring image of the Roadside Garden… Much of the ground cover is provided by Wild Strawberries (Fragaria virginiana), which we transplanted here from other parts of the Creekhouse garden. The yellow flowers are Golden Ragwort (Senecio aureus), transplanted here from another garden down the road. In nature, this species occurs only in wetlands. The pink patches are Carolina Pink (Silene caroliniana), propagated by Project Native. This species is listed as rare in NY State and we have seen it in only a few places in the high Taconics and along a roadside in Copake. Also present in the Roadside Garden (as in many other places in our garden) are Columbine (Aquilegia canadensis), transplanted here from a forgotten corner behind the Farmstore.

Let’s switch our focus to the Rain Garden, which was designed to catch at least some of the runoff from the parking area in front of the Creekhouse and to create an interesting habitat full of seasonal color changes and rich in insect and bird life near the main entrance.

It is composed of a variety of shrubs and perennials which grow in dense profusion and maybe somewhat “disorderly” fashion. But do come closer and have a peek who all is hiding in this lively spot…

This lovely trio of shades of red are Cardinal Flowers (Lobelia cardinalis), Swamp Milkweed (Asclepias incana), and Showy Ticktrefoil (Desmodium canadense). All three were grown from seeds collected in the wild and raised in pots in our “nursery” below the porch of the Creekhouse. Hummingbirds have been frequent visitors to the Cardinal Flowers and Monarchs and other butterflies can’t get enough of the Milkweed nectar.

Great Blue Lobelia (Lobelia siphilitica) is a botanical cousin of Cardinal Flower and known in Columbia County only from a handful of calcareous wetlands. These plants were transplanted from the garden of David Lewis and Ellen Winner in Hillsdale.

The bold white Turtlehead (Chelone glabra) is found in many wet meadows and swamps. These plants all grew from a single potted plant propagated by Project Native. We are yet waiting for a Baltimore Checkerspot butterfly to discover these plants to lay its eggs on and raise its caterpillars. A Viceroy butterfly had discovered the willow shrub in the Raingarden and a “bird poop” caterpillar typical for this species was feeding for a few days on its leaves. Unfortunately, when we finally got around to taking its picture, it had disappeared.

A little known plant worthy of more attention by native plant gardeners defines one border of the Rain Garden.

For weeks now, it has been producing its lovely yellow flowers and its peculiarly-shaped fruits, one at a time…

In another month, the foliage of Seedbox (Ludwigia alternifolia) will turn a deep dark red and the red fruits remain on the plant into the winter. This is another species that we rarely see in the wild, but which readily reproduced in our “nursery” from seeds collected on a pasture right here at Hawthorne Valley Farm.

Finally, one of the shrubs in the Rain Garden is Bottonbush (Cephalanthus occidentalis).

Sadly, it is a bit slow in leaving out in the spring and its lovely white flower balls last only for about a week. However, while in bloom, the flowers attract a multitude of insects, such as this flower fly (possibly Temnostoma vespiforme). This shrub occurs in the wild in a variety of wetland habitats and is often the dominant shrub in so-called kettle-shrub-ponds. These ponds now fill depressions that were formed by chunks of ice left behind by a retreating glacier.

Back in June, the Rain Garden was dominated by the white flowers of Beardstongue (Penstemon digitalis), transplanted here from the Roadside Garden, and the white flower clusters of Elderberry (Sambucus nigra var. canadensis). The showy flower stalks of early-blooming Angelica (Angelica purpurea) are also visible in the foreground.

And all the way back in May, it was still somewhat of a mystery to see who had survived the winter and would fill in the garden bed as the season progresses…

The Shade Garden is slowly taking shape under the big Honey Locust tree south of the Creekhouse.

Here, we have invited a variety of woodland ferns, sedges, grasses, spring ephemerals, as well as shade-loving asters and goldenrods. Work on this garden bed only began a year ago and it still has a “young” feel to it. Most of the asters and goldenrods grown from seeds collected last fall are not yet going to flower this year.

Along the “weedy” fenceline between the parking lot and the pasture, we began to enrich the vegetation with New England Aster (Aster novae-angliae) seedlings grown from seeds collected along Harlemville Road last fall. The seedlings will be protected from competition by a layer of mulch for a couple of years and then they’ll be on their own to hold their place… We are eagerly waiting to see if any of the seedlings are strong enough to produce flowers this year.

In the meadow (former lawn) below the fruit trees, we also began to transplant New England Aster seedlings, as well as established Beebalm, Mountain Mint, and Beardstongue from the Roadside Garden.

And while I wrap this up, the hummingbirds continue to visit the Cardinalflowers in the Rain Garden and the Monarch caterpillar munches happily on the leaves of Common Milkweed in the Roadside Garden. It’s elder sips nectar from the Swamp Milkweed, while the Milkweed Beetle is going about its own business…

If you would like to see pictures from the very beginning of the Creekhouse Garden, please check the blog from 21 July 2011. I also would like to extend an invitation to all of you to come visit the garden in person. Thursdays 6-8pm is a great time, because we are always here for open house. If you are hoping to come some other time, please give us a call to make sure, somebody will be here to show you around. You are also welcome to just stop by and look around on your own! The Creekhouse is located at 1075 Harlemville Road in Ghent. Our phone is (518) 672-7994.

Finally a great big THANK YOU: Many people have contributed with their expertise, with plants and seeds, and with muscle power to the conception and realization of the Creekhouse Garden. Foremost I would like to thank Ruth Dufault and her crew, who really got us started. We also received valuable advise from Judy Sullivan (formerly Project Native), Linda Horn, Tina VanDeWater, and numerous other native plant gardeners and landscapers. Additional hands-on help came from the garden crew here at Hawthorne Valley, the FEP summer interns and several volunteers. I would like to particularly thank Anna Fialkoff for her enthusiastic help and expertise with the native plants and Ken Kilb for his steady support with weeding, hole-digging, transplanting, and mulching during this year. The garden would be much poorer if it hadn’t been for these two wonderful people!

This posting gives an update on the Native Plant Garden around the Creekhouse here at Hawthorne Valley. Our  goal with this garden is to showcase native plants with ornamental potential, provide a sanctuary for rare natives and their associated insects, and inspire more people to choose native plants as part of their own garden designs. Many native plants have become extremely rare in the wild, so please, never dig them up in their natural habitat, unless the habitat is about to be destroyed. If you do collect seeds from the wild, please collect them only where there are plenty and take only a small proportion of the seeds to ensure the sustainability of the wild population. Throughout this posting, I will point out where the plants in our garden came from. We are happy to swap seeds and plants with other native plant gardeners.

And should you get sick and tired of looking at late fall images of the garden, remind yourself how the garden looked at the height of the season with the images in the post of July 21, 2011.

When you drive by the Creekhouse these days, you see the Roadside Garden slowly going to sleep for the winter. However, there is still a lot going on…

We left most of the seed heads on the native asters and other plants, so there are still interesting patterns of color and texture to look at. As a side benefit, the seeds remain available as food for animals.

Aside from the rather dry-looking stalks and seed heads of grasses and asters, etc., there is still an amazing amount of green in the garden bed.

Golden Ragwort or Groundsel (Packera aurea, formerly Senecio aureus) provides a nice ground cover with its rosettes of ovate leaves. Golden Ragwort is locally abundant in swamps throughout the county, but these plants had been transplanted here from another ornamental garden last fall. The dry spikes on the left are Great Lobelia (Lobelia siphilitica), which was bought from Project Native and planted here last fall.

Another Great Lobelia (Lobelia siphilitica) forms its own rosette of green leaves. We know Great Lobelia in the wild only from a handfull of places in calcium-rich wet meadows in the eastern part of Columbia County.

Amidst a rigorous ground cover of Wild Strawberry (Fagaria virginiana), transplanted here from another part of the Creekhouse garden, thrives the tender but prolific American Harebell (Campanula rotundifolia). Note its blue bell-shaped flowers which it presented continuously since June and is still not ready to give up… This plant was bought from Project Native and is very rare in the wild: we know of a single spot where it grows in Columbia County on top of the Taconic Ridge in Copake.

Hiding in the shade of the rock is another great ground cover: the velvety leaves of Pussytoes (Antennaria sp.). Pussytoes are not uncommon in dry meadows and on banks along roads. This one was transplanted from another garden.

This is the rosette of a Carolina Pink (Silene carolinensis), which was bought from Project Native and planted here in the fall. This species is rare throughout NY State and in our County we have seen it at only two locations, both in Copake.

Wild Lupine (Lupinus perennis) has been known historically to occur in the south-western corner of the town of Hillsdale. We have not yet been able to re-locate this only known population from the County. Wild Lupine is one of the flagship species of the Albany Pinebush and host plant to the federally endangered Karner Blue Butterfly (Lycaeides melissa samuelis). Although the Karner Blue is highly unlikely to ever show up in our yard, I got this plant last summer on sale at Agway and it has rewarded us with beautiful blue flowers way into the fall.

And here is the Rain Garden which collects and channels the runoff from the parking area…

All the native wetland shrubs we had bought from Project Native in the spring for this part of the garden have gotten well established and have been left alone by the deer (knock on wood!).

Red Chokeberry (Aronia arbutifolia) is still presenting its red berries.

The sturdy sporophylls (= “spore-bearing leaves”) of Ostrich Fern (Matteuccia struthiopteris) have great ornamental value throughout the winter. We have Ostrich Fern from Project Native as well as some plants transplanted from a friend’s garden in the Rain Garden.

The pale leaves and stalks of Purpletop (Tridens flavus) contrast beautifully with the reddish hues of Bayberry (Myrica gale). While the latter came from Project Native, we proudly grew the Purpletop from seeds given to us by a friend last fall!

A rather indestructible native plant common to many roadsides in our area is Beardtongue (Penstemon digitalis). It was already established among the grasses along our roadside and we have transplanted it from that population to a variety of locations within the Native Plant Garden, where we now enjoy its sturdy late-season rosettes.

Another very sturdy rosette is formed by Cardinalflower (Lobelia cardinalis), which we grew from seeds collected last fall here on the farm. The seeds of Cardinalflower are tiny, almost dust-like and their newly-germinated seedlings looked rather fragile. But as soon as they were in the ground, they grew vigorously and now we are looking forward to next year’s flowers.

This Indian Grass (Sorghastrum nutans) was bought from Project Native this spring and has gone through an array of beautiful colors, including beautiful shades of green and pinkish-purple, until it finally settled on its late fall tan.

This Great Angelica (Angelica atropurpurea) came from Project Native and is still taking its time to go to sleep for the winter.

This little well-armed shrub is a native Swamp Rose (Rosa palustris) we grew from seeds collected in a swamp on the farm last year. This species is distinct from the invasive Multiflora Rose. It likes “wetter feet”, its flowers are pink (not white), and both its flowers and rose hips are bigger than those of Multiflora Rose.

Somewhat covered by the dried leaves of Sweetflag (Acorus americanus) is another rosette of still-green leaves: Yellow Avens (Geum allepicum), grown from seeds collected in a wet meadow on the farm last summer.

Unperturbed by the late season stands Mountain Mint (Pycnanthemum sp.), grown from seeds collected on a dry hillside here on the farm last fall.

This newly cultivated area is our attempt to create a Woodland Garden surrounding the large and established Honey Locust tree, which is not native but tolerated for the shade it gives to the house.

After smothering the weeds with newspapers and covering the newspapers with bark mulch, we planted examples of native woodland plants, such as this Plantain-leaved Sedge (Carex plantaginifolia), which came from Project Native.

We also started a little fern glen with ferns from Project Native, including Christmas Fern (Polystichum acrostichoides), Marginal Woodfern (Dryopteris marginalis), Hairy Lipfern (Cheilanthes lanosa) seen on this picture, plus several other species not depicted. The grass-like green leaves sprouting all throughout are the invasive Garlic Grass (Allium vineale) which had been growing in this spot before and has found its way through the newspaper and mulch…

Another recently cultivated area is around these wonderful established stone steps below the Honey Locust tree.

We began by establishing the beds, claiming the space with mulch and then transplanting Columbines (Aquilegia canadensis) from another garden area on the farm.

We call this area the “Wild West Hill” and our efforts to date have been focused on watching which native plants want to grow there and trying to discourage the invasive Multiflora Rose (Rosa multiflora), Teasel (Dipsacus laciniatus), and Honeysuckle (Lonicera spp.), who would gladly take over this space in no time. We are also discouraging two of the native Goldenrods, Canada Goldenrod (Solidago canadensis) and Wrinkle-leaf Goldenrod (Solidago rugosa), who are all too happy on this disturbed hillside and hope to increase wildflower diversity by creating small “native wildflower islands”.

Another “wild” area is this dry grassland near the road. It actually has a nice variety of uncommon Goldenrods, such as Early Goldenrod (Solidago juncea), Silverrod (Solidago bicolor), Grey Goldenrod (Solidago nemoralis), and Bluestem Goldenrod (Solidago caesia) and so far, our management consisted of discouraging the Wrinkle-leaved Goldenrod to take over the area.

Along the wooded roadside and also around the foundation of the house, Herb Robert (Geranium robertianum) is a common sight. We know it from several calcium-rich forests and rock outcrops throughout the County and consider it a native species that we welcome to volunteer in the Creekhouse garden.

A Hawthorn tree by the parking area had a mockingbird nest this summer. Now, that the leaves are down, it turns out that the nest has found another purpose as the pantry and dining hall of some small rodent, who filled it with hawthorn berries.

I would like to thank Ruth Dufault and the many other people who have helped shape the Creekhouse Garden with their knowledge and ideas, their muscle power, their patient weeding, and/or with plants and seeds from their own gardens. This would not have been possible without you!

More Fall Flowers

Did I say in the last posting that we were at the peak of the fall flowers? Well, it has been a long peak and there are still many flowers in the Valley, as well as striking displays of fruits. So, I hope you will tolerate (and maybe even enjoy) another botanically focused blog.

For those of you who can’t visit Hawthorne Valley on a regular basis, this is how the landscape presents itself at the moment as seen from the Creekhouse on Harlemville Road:

The pastures are still amazingly green. The trees are very slowly beginning to change color…

Along the edges (and in less intensively grazed areas) bloom a profusion of white, yellow and purple flowers of the aster family.

from the distance…

and close up.

But before delving a bit deeper into the diversity of asters and their close relatives that make up the bulk of flowers at this time of the year, I would like to share some other noteworthy botanical discoveries from last week.

These gorgeous deep purple berries are the fruits of pokeweed (Phytolacca americana), which grows here and there along field edges. One can be seen north of Ben Ocean’s bridge behind the school. Pokeweed has dangerously poisonous roots, seeds, leaves and mature stems. However, in the spring, the young shoots are supposedly edible if prepared correctly. I have never tried to eat this plant but delight in looking at it… Pokeweed is native to our area, but sometimes has a tendency to grow profusely in places with bare soil and in some peoples’ gardens.

Another autumn delight for the eye are these hairy fruit heads of virgin’s bower (Clematis virginiana), which is usually found in moist soil near streams or in swamps.

These unusual fruiting capsules belong to a rare native plant called seedbox (Ludwigia alternifolia). We have found this species in the wild only in two places, so far: on the “Solar Field” here at Hawthorne Valley, where it grows in a wet spot along the eastern fence line (see picture below) and on another farm in Kinderhook. The seed capsules contain tiny seeds which readily germinate. Seedbox is now also thriving in the native plant garden at the Creekhouse.

This is how seedbox looks from further away: the two reddish plants along the fence line.

Nearby, on the North Hill, but also by the Firepond and in Indian Valley, as well as in many other fence rows, we currently have a phenomenal harvest of autumn olive (Eleagnus umbellata). Now there is an edible plant that is waiting to be picked! Raw, the berries are a bit too tart for my taste, but they make delicious fruit leather and I have some berries in the fridge waiting to be made into jelly…

Autumn olive is originally from Asia and is considered an invasive plant because of its tendency to take over old fields, so you have to have no trepidations in harvesting as many berries as you can get your hands on.

These red berries are found in the forest.

They belong to a native plant called false solomon’s seal (Smilacina racemosa).  Peterson’s Field Guide to Edible Wild Plants states that the berries are edible but are mildly cathartic (which means they might give you “the runs”) and I don’t know of anybody who eats them

Another plant with red berries growing in our forests is Jack-in-the-Pulpit.

At this time of the year, the leaves and spathe/spadix (who originally surrounded the flowers and young fruits) have withered and the ripe berries are ready to be picked by birds and box turtles. The berries are not edible for people, because they contain calcium oxalate.

Not all fruits are red, at this time of the year!

These curious little “chinese lanterns” were found in the meadow near the swimming pond and are the old fruits of ground cherry (Physalis sp.). The edible berries that were ripe inside the lanterns earlier in the summer, were obviously never found and are now rotting inside. Which is not to say that the seeds won’t germinate next spring…

Now, we’ll slowly inch our way from fruits to flowers.

This lovely little orchid (around here, it is usually 4-6 inches tall) is called nodding ladies’ tresses (Spiranthes cernua) and is currently flowering in at least three different locations on the farm. It likes wet meadows and seepy areas, but at each location there are only very few plants.

The exact opposite are several profusely growing smartweeds (Polygonum sp.).

Which, upon closer inspection, have almost orchid-like flowers, themselves…

This species is the native Pennsylvania smartweed (Polygonum pensylvanicum). It is characterized by its dense flower heads of pink or white flowers and the conspicuous glands on the stem just below the flower heads.

But other smartweed species grow nearby on the edge of the Beefield.

Left to right, you can compare the introduced waterpepper (Polygonum hydropiper), with narrow, elongate and nodding inflorescences of whitish flowers and leaves that are extremely peppery to the taste; the native Pennsylvania smartweed (P. pensylvanicum), with its glandular stems; and a third, yet unidentified, species with slightly smaller flowers and smooth stems.

And, finally, the Aster family (which was introduced in the last blog posting):

Annual fleabane (Erigeron annuus) is a native member of the aster family that begins flowering in May and can still be seen in full bloom at this time of the year along field edges and in extensively grazed pastures. To me, the biggest difference from the “true asters” is that the disk flowers of fleabane don’t seem to change color as they mature. Or at least one doesn’t get to see it, because the ray flowers turn from white to pink and fold themselves up to cover the maturing disk flowers (see bottom left flower head).

You can see the change in color of the disk flowers from yellow to purple in the left (more pinkish) aster below:

The color of the ray flowers in New England aster (Symphyotricum novae-angliae) does not change with time but is a characteristic to each plant. This picture shows a (rarer) pink and a (more common) purple form growing next to each other. Where you see a clump of pink New England aster, you will likely see another clump next year.

The wet meadow west of the former Banjo Mountain Cafe, like many other wet meadows, is currently dominated by the lavender flowers of purple-stemmed aster (Symphyotricum puniceum).One clump of New England aster (purple flowers, bottom right) contrasts with the sea of purple-stemmed aster (lavender flowers). Below, a close-up comparison of the two species:

Purple-stemmed aster (lavender and whitish flowers on left) tends to occur in wetter places and usually has at least somewhat toothed leaves, while New England aster (purple flowers on right) tends to occur in dryer places and its leaves are never toothed. Both are rather hairy, can have purplish stems, and have sessile leaves with clasping leaf bases.

Road banks are a great place to spot asters. This site on Harlemville Road has at least five species growing next to each other.

Smooth-leaved aster (Symphyotrichum laevis) has lavender ray flowers and the entire plant is super smooth, almost waxy.

The leaves of smooth-leaved aster are narrow, sessile, and not at all toothed.

Right next to it, on the dry road bank, grows heart-leaved aster (Symphyotrichum cordifolium), which has a very similar ray flower color, but very different leaves.

The leaves of heart-leaved aster are heart-shaped (at least the ones low on the plant), rough to the touch, strongly toothed, and have a long, sometimes slightly winged, petiole.

Dry road banks are also a good place to spot wavy-leaved aster (Symphyotricum undulatum), another species with lavender ray flowers.

The leaves of wavy-leaved aster can be hairy or smooth, toothed or not, but they always have a distinct winged petiole which clasps the stem in a characteristic way.

Willowleaf aster (Symphyotricum praealtus) is another species that likes to grow in the open, often along field edges. It has ray flowers that are almost white with just a hint of lavender. It is superficially very similar to panicled aster, but distinguished by its narrow, willow-like leaves.

The leaves of willowleaf aster are never toothed (those of panicled aster usually have at least a few teeth) and have a characteristic, isodiametric network of secondary veins.

Finally, I would like to share a few aster species from the shaded forest understory with you:

This picture from near Ben Ocean’s bridge contrasts white wood aster (Eurybia divaricata) in the foreground with Schreber’s aster (Eurybia schreberi) in the back. The almost ubiquitous white wood aster has narrower, more strongly toothed leaves and its flower heads tend to be arranged in a flat-topped inflorescence. The rarer Schreber’s aster tends to have more elongate inflorescences, the leaves are broader and the colonies tend to be composed of flowering plants as well as a ground cover of basal leaves.

Another rarer woodland aster is large-leaved aster (Eurybia macrophylla). It is superficially very similar to Schreber’s aster, but the ray flowers tend to have a lavender tinge and a magnifying glass reveals tiny glands that cover the stems near the inflorescence. A patch of this aster grows west of the Baba Yaga house at the base of Phudd Hill.

Two goldenrod species are currently very prevalent in the forest along the Agawamuck:

Zig-zag goldenrod (Solidago flexicaulis) has broad leaves and a stem that tends to zig zag from one leaf to the next. It prefers the deep alluvial soil near Ben Ocean’s bridge.

The flowers of zig-zag goldenrod are not arranged at the top of the stalk and above the leaves, like in most other goldenrods, but grow from the axils of the leaves, thus alternating with the leaves along the stalk.

Bluestem goldenrod (Solidago caesia) grows in slightly dryer, but also shaded habitat. Some nice patches can be observed on the trail to the swim pond.

Bluestem goldenrod also alternates flower clusters and leaves. The leaves are long and narrow, the extremely smooth stem is sometimes bluish/purplish-colored and often has a waxy cover that can easily be wiped off.

Farm Creek Corridor

This posting was prepared before “Irene” came through and I am sending it off from our vacation spot in Canada. Anna, who is holding the FEP fort in Harlemville, assured us that, although there was flooding at Hawthorne Valley, it was not as extensive as two years ago and has all receded by now. Sorry, no pictures from the flood, because we were not there to witness it. However, this blog is about the corridor along the farm creek: For at least six years now, the corridor along the farm creek from the pump house to the cattle crossing has not been grazed. The cows were fenced out and the vegetation was left to develop for a while, to see what would come up. The invasive multiflora rose got a bit more common than desired and removal of this aggressive species in the creek corridor has begun last year. A few other invasive species are present in smaller amounts and might need to get discouraged in the future. Other than that, we are pleased to see many native shrubs and wildflower species thriving along the creek, creating a structurally and botanically diverse habitat that attracts a lot of insects and birds, protects the creek from surface runoff, and begins to shade sections of the creek. Here is a mid-summer inventory (pictures mostly by Lauren McDonald) of the  colorful and vibrant habitat that we now find along the creek.

A view from the edge of the water with the native Agrimony, Goldenrod and Boneset flowering on the shore in the bottom left corner, the native Tussock Sedge growing along both shores, the invasive Purple Loosestrife flowering in the center, surrounded by the native Joe-Pye-Weed, Coneflower and more Boneset.

A view from the “outside” of the corridor. Amongst the woody plants in the background (near the stream) are native Willows and Sumach, and the invasive Multiflora Rose which is overgrown by the white-flowering native Virgin’s Bower.

Virgin’s Bower also takes advantage of the deer fence surrounding the vegetables in the “main field” just west of the creek.

Some sections are overgrown by this orange, spaghetti-like plant called Dodder. Dodder is a native, parasitic plant that does not bother to grow leaves or any other green tissue and can not photosynthesize. It steals nutrients from other plants by tapping into their roots. It thrives in many wetlands throughout Columbia County.

Another type of climbing plants (though not parasites) in the farm creek corridor are the two species of Tear-thumb. You’ll know them when you touch them, as the recurved hooks along their stalks (which come in handy when they try to get a grip on other plants) do just what their name suggests: tear thumbs… The picture above shows the more common Arrow-leaved Tear-thumb, and the picture below the rarer Halbert-leaved Tear-thumb.

Both Tear-thumbs are members of the buckwheat family (which also includes knotweeds and smartweeds) and are characterized by clusters of tiny, orchid-like flowers in shades of white to pink.

Bittersweet Nightshade is a non-native climber related to tomatoes, potatoes, eggplant and peppers. It thrives in many of our wetlands and also can become a weed in vegetable gardens.

One of the most conspicuous insects along the farm creek is the Ebony Jewelwing, a damselfly. Its larvae are aquatic, like those of many other insects, and the adults are often seen hunting for flying insects along creeks.

Spiders also know where there is an abundance of insects. Did this spider build its web in a thorny Multiflora Rose on purpose? Many birds like to nest within the protective thorns of the rose…

We don’t know if this little sparrow actually had a nest in the farm creek corridor or was just visiting to check out the food situation.

Swamp Milkweed (big pink flower clusters) is an important nectar plant and also host to the caterpillars of monarch butterflies. Here it grows intermingled with Spotted Jewelweed (orange flowers) and Dock-leaved Smartweed (white flower clusters). All three of these wildflowers are native to Columbia County.

We did not spot any Monarch caterpillars along the farm creek. They are generally not very common this year. But we do have this one munching on one of our Swamp Milkweeds in the roadside garden in front of the Creekhouse.

Less conspicuous, but pretty ubiquitous, is this Willow-herb. Its tiny pinkish-white flowers develop into plenty of feathery seeds which will fly off in great numbers in the fall.

Another rather inconspicuous plant along the creek is Wild Mint, which we often first notice by the delicious smell it exudes when stepped upon.

Monkeyflower, a native relative of the Snapdragons of our gardens, adds some blue to the flower landscape and likes to grow right next to the water.

Blue Vervain is another native wetland plant that thrives in the farm creek corridor. It is related to Lemon Verbena, and I often get asked if it is also a medicinal plant. According to Peterson’s Medicinal Plant Field Guide, native Americans have used the leaf tea as a “female tonic”. It was also used for colds, coughs, fevers, bowel complaints, dysentery, and stomach cramps. It large doses it is reported to be an emetic (induces vomiting). Modern herbal uses include headache and rheumatism relief and tranquilizer. The Peterson Edible Wild Plants guide reports that its tiny seeds can be made into a somewhat bitter flour.

Blue Vervain has a cousin, the White Vervain, which tends to be more of an upland species, but is common along the higher shore of the farm creek. It’s tiny white flowers (which individually look basically the same as those of the Blue Vervain, just paler) are arranged much more loosely along the spreading inflorescence spikes.

The picture above shows the sprawling White Vervain.

An exciting find along the farm creek this year was the frequent occurrence of an otherwise rare hybrid Vervain (Verbena x engelmannii), which is intermediate between Blue and White Vervain with its lavender-colored flowers that are not as tightly packed along the inflorescence spikes as in Blue Vervain, but also not as loosely arranged as in White Vervain…

In the foreground, an example of a Hybrid Vervain (tiny, lavender-colored flowers on long spikes), surrounded by Green-headed Coneflower (yellow flowers) and Joe-Pye-Weed (whitish to pink).

[This week’s blog is written by our departing interns Lauren McDonald and Emily Reiss; not only have they been helping us here at the Farmscape Ecology Program, but they have also been spending long hours helping out on the Farm itself. This blog describes a bit about what they have seen on the Farm of late.]

Just as in the natural areas we explore in Columbia County, the farm itself constantly changes with new and exciting happenings every week as different crops are planted, harvested, and turned under; the insects pollinating them arrive, mate and lay eggs; and new weeds sprout, flower and go to seed. When living and working on the farm, these natural cycles and the changing of seasons become integrated into the forefront of our consciousness and planning, not just the backdrop to a daily routine.

Right now we’re in full-on summer mode with tomatoes, peppers, eggplant, basil, green beans, cucumbers, and zucchini all coming in along with lettuce, chard, beets, carrots, kale, fennel, cauliflower, and more. Between the cultivated and non-cultivated plants, insects, birds and other animals on the farm, the fields are diverse, dynamic places to explore. Here are some pictures of what’s growing on the farm (both what was planted and not) and some of the animals who have made their homes in the vegetable gardens.

It’s especially interesting to compare some of the cultivated varieties to their related, non-domesticated weedy competitors.

For example, horse nettle (Solanum carolinense var. carolinense), a member of the nightshade family of plants, is quite prolific in parts of the Corner Garden. However it does seem to be popular with both bees (can you see the bumblebee in the picture?) and flea beetles, so it is useful to have around for attracting pollinators and keeping flea beetles from eating holes in the eggplant and brassica leaves. Thank goodness none of the delicious cultivated nightshades like tomatoes, peppers, and eggplant have the vicious spines of horse nettle!

Here is the horse nettle flower,

and a tomato flower (& 'fruit')….

an eggplant flower (& 'fruit')…

…and a pepper flower (& 'fruit').

Similarly, bittersweet or climbing nightshade (Solanum dulcamara var. dulcamara) grows along the farm creek, and you can see from the poisonous fruits why Europeans were originally wary of tomatoes and other nightshades brought over from the New World.

They say that carrots love tomatoes, so the Corner Garden is experimenting with companion planting of the two.

This red/purple amaranth is a weed in the Corner Garden, but ...

its relative in the Amaranthaceae family, Swiss chard, is one of the most popular greens on the farm.

Queen Anne’s Lace or Wild Carrot (Daucus carota), Fennel, and Carrots of the Apiaceae family all grow in the gardens as well.

This is the Corner Garden fennel.

You can see the similar umbellate inflorescence of these wild carrots on the edge of the field.

And this is an impressive head of green oakleaf lettuce that bolted, or started to prepare to flower and go to seed.

The plywood greenhouse with the next successions of basil, lettuce, kale, and more.

Here are the beds of Siberian Kale in the Main Field.

Then zooming in, here are the eggs of a cabbage butterfly on the underside of a kale leaf.

In this winter squash flower you can see a striped cucumber beetle, a spotted cucumber beetle, and likely a Peponapis bee. The bees in the Peponapis genus are North American natives that specialize on the Cucurbitaceae family (squash, melons, gourds etc.). They originated near Mexico with their squash hosts, and have followed the movement of squash plants north with indigenous and later European cultivation. They are by far the most important pollinator for squash plants, but you’ll also find other bees and pollinators getting in on the action too. Unlike the honey bee and other social bees, Peponapis are solitary bees and dig holes (easily a foot deep) in the ground to lay eggs and raise young.

Thanks to the efforts of this Honey Bee and others, we’re starting to see...

small watermelons in the Corner Garden.

Bumble Bees are not as discriminating as Peponapis in their floral selection. They are well known for their tomato and other nightshade pollinating (remember the bumble bee on the horse nettle earlier), but can also be found enjoying red clovers, ...

and helping out the Peponapis (though they probably don’t need it) on Cucurbitaceae (melons, squashes, cucumbers and the like).

Joe Pye Weed planted in the Corner Garden. It grows along streambeds and in wet areas throughout Columbia County and is also quite popular with the bees.

Both native and non-native ladybugs are quite common in the gardens, and are incredibly valuable in eating aphids off the plants. This one is native,

but this one, which you might be more used to seeing, originally came from Asia.

Both can feast on these aphids though, shown on a chard leaf.

The Japanese beetles have done a bit of damage to basil, but thankfully not too much else. They can devour entire leaves except the veins and completely destroy plants.

Here is a head of red cabbage that can be harvested soon.

The Meadow Fritillary is a native butterfly that not surprisingly prefers meadows and other open areas for the abundance of their host plants, violets. The initial colonial clearing of land was a boon to the Meadow Fritillary, but once tilling and crop cultivation became more common, the important violets were not as available. The Meadow Fritillary is now gone from eastern Massachusetts, though it remains in the western part of the state. Although this butterfly was found in the vegetable gardens, most of the open land surrounding the vegetable fields is either cut for hay, or used for cow pasture, practices which might maintain the low-growing violet population for the Meadow Fritillary.

Birds on the farm are a great assets especially when they eat pests. When they (mostly crows) start going for the tomatoes though, it’s less ideal. These pie tins on the stakes in Main Field reflect light and make noise in the wind to scare the birds away.

These two killdeer are probably protecting one of their small, unassuming nests laid on open ground, often right in the fields. If you get too close, the male will shriek and the female will pretend to have a broken wing to sacrifice herself for their young. These are some of the grassland breeding birds that can use farm fields as analogies to their original coastal, wet meadow or prairie-like habitats.

See what the site of our visit looked like from the air in 1942 or 2009. (The yellow circle indicates the location of the rocky, dry slope where we ended our outing). Note especially the extent of forest.

keywords: old field, ants, butterflies, grass

What was once forest is now field with forest creeping in from the edges and from toe-holds within the fields. The field in the foreground is dominated by European grasses and weeds, although here and there native plants such as Little Bluestem and Milkweed appear.

The thistle on the lowlands, an exotic weed, has passed from flower to fluff; the wind was carrying the tufts off like feathered balloons.

This Buckeye butterfly flitted across the field as we arrived. Buckeyes don't overwinter in our area; rather, they are migratory. In some years, such as this one, there seem to be more of them about. In other years, we don't see a one.

Also present are old field butterflies like this Northern Broken Dash, here perched atop Spotted Knapweed. Its caterpillars feed upon our relatively common "panic grasses". Neither those grasses nor this butterfly are very common in these fields.

We have seen few Monarchs this year, but there were several dodging back and forth across this field when we visited. Apparently, they were able to find the scattered clumps of Milkweed...

This Monarch caterpillar is well on its way. Monarchs aren't the only insects using the Milkweed. There were Black and Red Milkweed Beetles. And some plants are spattered with aphids.

These yellow aphids are being tended by the "Somewhat Silky Ant", a common visitor to field, home and picnic. Its silvery sheen is caused by a fine coating of hairs over most parts of its body.

The silver sheen of the "Somewhat Silky Ant" is better seen in this photograph of two ants comparing notes on a Milkweed leaf.

The big eyes and dark coloration of the "Somewhat SIlky Ant" are perhaps typical of ants that spend much of the day out and about. However, across our various ant species, there is much variation in body size, texture, color and shape.

Forest edges into the field both spontaneously (when pieces are abandoned and reforest through the natural return of woody plants) and through plantings. These Scotch Pine were planted decades ago on an abrupt ridge that was probably difficult to farm.

Within that same pine stand, one finds a cooler, somewhat moister microclimate (that's our dog poised in the clearing). We pick up a few forest-dwelling ants in this little pocket.

This is a "Broken-Back Ant" nest. These are generally woodland-dwelling species. Like most ants they'll eat a variety of foods (that is, they're 'omnivores'), but this group is also known to disperse plant seeds because of its predilection for the food packets that some sedges and spring flowers attach to their tiny seeds in much the same way that other plants create larger fruits, such as cherries or blackberries, which then attract birds who carry those seeds elsewhere.

This is a "Broken Back Ant", so-called because its thorax (the part behind the head) is long and contorted. It is also armed with sharp spines, as are the backs of several other groups of ants. Some say that such spines help protect the spindle-thin waist from attackers. Who knows. Ant society does not seem to be a peaceful place, and attacks from other ants seem common, so a tendency to evolve protection against such attacks seems possible. How much poking power these relatively short spines would provide is unclear.

This Sugar Maple was probably left in the middle of the field for shade. Given its distance from the farmhouse, it's hard to believe that tapping for maple syrup provided any motivation, although settlers did favor Sugar Maples, and our forest seems to have more Sugar Maples in it now than prior to European settlement. The low-hanging branches and adjacent fencerow can discourage grazers and hay makers, and form an initial 'crystallization point' for returning forests.

The butterflies and moths we find in these fields seem to have come in mainly for the nectar sources. The caterpillars of Spicebush Swallowtail, here seen drinking at a still-flowering Thistle, probably feed on its namesake in the adjacent wet forest.

Although the Spicebush strongly resembles the Black Swallowtail, it is slightly larger and, as this wings-open perspective shows, has a larger blue patch on its hindwings and less yellow.

Likewise this unfortunate Small-Eyed Sphinx, being eaten by the Jumping Spider attached to its abdomen, has caterpillars who feed on woodland plants such as Cherries and Shadbush.

This rocky prominence is slowly reverting to forest. The thin soils may have been made even thinner by the work of grazers' hooves which sloughed the delicate mantle of dirt off of the smooth bedrock. Left to its own devices, this area supports many of our native plants. These are more adept at living on such lands than the European plants brought over to grow in rich gardens or farm fields. The tall, bright green grass to the left of the rocks is Little Bluestem.

Little Bluestem grows in discrete bunches and is a 'warm season grass' meaning that its most exuberant growth occurs relatively late in the summer when many of our other grasses are beginning to look more 'tired'. In autumn, it will add a beautiful almond haze to this hillside.

This Spirea, Steeplebush, also grows in the rocky 'savanna' (savanna refers to an area where woody plants are interspersed with large areas of more open lands). Meadowsweet, a white Spirea, grows nearby here; both are native to our area.

"Sweetfern" is, in fact, no fern at all. But it does have fern-like leaves and when those leaves are crushed, they are sweetly aromatic.

Reindeer Lichen (so named because reindeer reportedly eat a tundra relative) grows thick and brittle on the rocks.

Nestled in one clump of lichen was this ant nest (the rock that covered it has been put to one side).

The nest in the previous photograph and the one in the photograph here are of small "Lasius" ants. These ants apparently live most of their lives below ground, tending and 'milking' various root-dwelling insects.

As perhaps befits their underground life style, Lasius tend to be paler ants with relatively small eyes. At least one of Lasius species is holarctic meaning that it naturally occurs in both North America and Eurasia.

These red and black "Formica" ants are common midst the rocks and dry vegetation (indeed, in our neck of the woods, ants generally seem more common in dry areas; somewhat the reverse of ground beetles). There are various kinds of such ants, but almost all are raiders of other ant's nests or frequent victims of such raids. Apparently, the majority of such raids are in search of forced recruits to the ranks of the raiding nest's workers, rather than attacks for food (although that happens too) or attempts to oust other ants from preferred nesting sites. Many of these are 'mound building' ants such as those also mentioned in our 13 May 2011 blog entry. Compare the profile of this ant to that of the "Broken Back Ant" pictured earlier - there's a lot of room for variation in the architecture of what we just generally describe as 'ant'!

This is the mound of one such ant, albeit from May and from Hawthorne Valley itself. It is however located in the same kind of dry, rocky habitat. The choice of such habitat may be due in part to the fact that it tends to stay open (due to the rocks) and yet is rarely subjected to the intense mowing or grazing that would quickly destroy the mounds. That said, many mound builders can and do make less conspicuous nests.

Aside from the ants in this 'savanna', some of whom are generally described as forest-dwellers, other insects also hint at a woody future. This Brown Stink Bug, pictured here on the somewhat unnatural background of my backpack, apparently feeds most commonly on oaks.

Perhaps including trees such as this Black Oak found nearby. Black Oak seems to occur in dry forests in our area - not as dry perhaps as where we find Chestnut Oak, but not as rich as prime habitat for White Oak or Red Oak (although both of these species were also in the neighborhood).

The future for this dry knoll? This shot, which looks like a green mish-mash, is full of some of the trees that may come to dominate. The Birch, whose gnarled trunk suggests senescence, may have come in when this was first abandoned open land. As the forest thickens, the Birch will probably give way to trees such as Shagbark Hickory, Red Maple, and those White or Red Oaks; all species who seem to have saplings in the foreground of this picture. Or perhaps, if some level of grazing is maintained by livestock or deer, or if a rare grass fire burns through, then the savanna and its ants and plants will persist for a bit longer.

While much of this blog was put together with ingredients from the sun-drenched fields, some of it happened here. At my nighttime desk, beneath the microscope, the only place where I can really get a good look at those ants, put names to them, and hence, add another ecological color - or level of understanding - to this landscape.

Native Plant Garden

Native Plant Garden at the Creekhouse

This posting is an update of our slow but steady efforts to create a native plant ornamental garden around the Creekhouse. During our inventories of wild-growing plants, we keep coming across native beauties that are well worth being cultivated as ornamentals. Furthermore, books like “Bringing Nature Home” make a very convincing point about the potential of ornamental gardens for supporting native biodiversity and overall ecological well-being of a region.

We’ll start at the beginning, pretty much a year ago, when Harlemville landscaper Ruth Dufault led a series of gardening workshops at the Creekhouse.

We began with an inventory of the plants that had established themselves around the Creekhouse and along the roadside in what was to become our “roadside garden”. We found that introduced grasses and common pasture weeds, such as Chickory and Wild Carrot, dominated the scene.

However, native beauties, such as this Beardtongue were also present, together with Common Milkweed, Asters, and Goldenrods.

We flagged the native plants we wanted to save, and then proceeded, with the help of many wonderful volunteers, to cover the unwanted plants with cardboard and newspaper.

The newspaper was covered with mulch and we had a “clean slate” to begin designing the roadside garden.

We began cautious planting with some potted plants from Project Native and with donated transplants from other gardens. The roadside garden was shaped to contain some areas with deeper, richer soil, where topsoil (from a construction site here on the farm) and compost (from the farm) were worked into the soil to allow moisture-loving plants, such as Joe-Pye-Weed and Swamp Milkweed, to thrive. Other areas of this bed were pretty much left with their original, very clayey soil and begun to be planted with drought-resistant native plants, such as Sweetfern and Butterfly Weed. All unplanted areas in the bed were initially covered with a generous layer of wood chip mulch. As the plants grow and new plants get added, the unplanted areas will decrease and we hope to eventually not need any more wood chips to keep moisture in the soil and to avoid excessive weed growth.

Last fall, we also got busy collecting seeds from wild plants that we thought might do well in our garden. Right here on Hawthorne Valley Farm, we found seeds of Blue Vervain, Swamp Milkweed, Seedbox, Monkeyflower, Beardtongue, Turtlehead, Yellow Avens, Cardinalflower, and a variety of sedges.

On Michaelmas workday, a crew of eager students helped us plant the first seeds into little pots so that they could overwinter outside, experience the wintery temperatures, and be ready to germinate in spring. Most of the seeds germinated beautifully with no special treatment, while we had no luck with any seeds from the aster family, including Joe-Pye-Weed, Boneset, or any of the Asters… I had been told that they need a few months of moist cold (think sitting in moist soil in a plastic bag in the fridge) before they can germinate, but didn’t heed that advise…

The last preparation last year was the digging of our future rain garden next to the parking lot and the removal of a big Multiflora Rose right at its edge. The Hawthorne Valley gardener Nate and his big machine made this effort look like child’s work…

This spring, Nate and his big machine helped us fill the hole with topsoil and compost and then we did one big spring planting with potted plants from Project Native, just to get the garden started. Again, we covered all unplanted areas with wood chips. Some of the mulch was promptly washed downhill by the first downpour, so now we have a bare intermittent creek bed traversing the rain garden.

Little by little, we then incorporated the seedlings we had raised from collected seeds as they became big enough for transplanting.

By June, the rain garden began resembling an ornamental garden bed…

The tremendous downpours of June were a good test for the rain garden and everybody (except for the mulch in the lowest parts) held up beautifully, even the Monkeyflowers we had planted smack in the center of the intermittent creek bed that transports runoff from the parking lot into the pasture. In fact, the cool and rainy spring helped all our transplants through the first difficult period. Not one was lost and the deer haven’t found them yet, either… Shhhhh!

The larger, purchased Turtlehead plants are surrounded by Turtlehead seedlings we grew from seeds collected last fall. The hope is, to eventually create large clusters of each species and to significantly reduce the amount of mulch needed.

We did not purchase plants of each kind we eventually want to establish in the garden. For example, these are seedlings of Cardinalflower…

and Blue Vervain…

… which we grew from seeds and will hopefully come into their own next year!

The rain garden now is a mix of shrubs, perennials, grasses, sedges, and ferns.

The roadside garden is beginning to fill in nicely with its mix of saved, already established plants (such as the Common Milkweed on the right), purchased potted plants (such as the Joe-Pye-Weed on the left), and donated transplants from friend’s gardens (such as the Turk’s Cap Lily in the front).

With the help of our tireless summer interns, we transplanted most of the saved Beardtongue into a neighboring, cleared area and then smothered the patch where they had been growing with newspaper and mulch. In spite of their being transplanted right before flowering season, they went right ahead and provided us with a wonderful display of flowers, anyway.

Ruth made sure to include some detailed stone work in the design, such as this…

or this…

and we tried to arrange the plant species for a pleasing combinations of color as well as texture and growth form.

Right now, we spend most of our garden time weeding and watering and hoping for the little seedlings to grow strong and fill in even more – and for the deer never to discover them…

Please feel free to stop by the Creekhouse any time to have a peek at how the roadside and rain gardens are evolving. None of the plants grown from seeds planted last fall are going to flower this year, but next year, we hope to showcase some of the uncommon native plants in their full glory.

This is just a beginning, there are large areas around the house that we have not even begun to transform, but this slow and steady approach should lead to a garden design that is appropriate for the place and our availability for maintenance.

This blog would not be complete without a big THANK YOU to Ruth Dufault (Bittersweet Gardens) and Judy Sullivan (Project Native) who helped conceptualize the Creekhouse Garden, to all the willing helping hands of landscapers, gardeners, volunteers and interns who did the groundwork, and to those who shared seeds or plants from their own gardens. I am looking forward to continue to work with all of you on the transformation of the weedy Creekhouse yard into an aesthetically pleasing and ecologically valuable native plant garden!

A Smattering of Local Literati and Nature.

On Easter Sunday, we do a short bike loop –  21C east to Harlemville Road, south on Harlemville Road to Ten Broek, east on Ten Broek to Pheasant Lane, south on Pheasant Lane until Phudd Road, and then back west on Phudd Road to Harlemville Road.

A cloudy, rainy but relatively warm day. We continue our exploration of the landscape as seen (or at least written about) by John Cowper Powys. So, in this installment, we’ll try to mix seasonal excerpts from his diary with our own natural history observations and photographs. To call Powys’ writings “complex” is, from what little I understand, an understatement. And yet, much of his diaries are simply recountings of his walks and wanderings about the land. As such, they help us understand the evolution of our local landscape.

A few words of thanks: Jacqueline & Max Peltier for having first contacted us from France. Jacqueline runs the web site which can link one to a world of people studying this English novelist who lived from 1872 to 1963, and who resided from 1930 to 1934 on the east side of Phudd Hill. Two of his most well-known works, Autobiography and Glastonbury Romance, were written while he lived at what he called Phudd Bottom. Jacqueline and Max have provided me with copies of Powys’ diaries, and those works provided the extracts given below: The Diary of John Cowper Powys 1930, edited by Frederick Davies and published by Greymitre books & The Diary of John Cowper Powys 1931, published by Jeffrey Kwintner. Via Jacqueline, Kate Kavanagh provided a very handy map, indicating the location of sites mentioned in Powys’ diaries. Thanks to all these folks for their generous sharing of information and resources.

John Cowper Powys and his long-time companion Phyllis Playter on the stoop of their Harlemville home in the early 1930s. The origin or exact year of the photograph is unknown.

Same house, Easter 2011.

Wandering chimneys, disappearing shutters, stone steps to the back door, but, ‘awl ‘n all’, not too different. However, look too at the landscape. The hill behind the house is at least partially bare. In the 1930s, this landscape was much more in fields. With this in mind, reading the diaries can be a bit like visiting a house you know but in which they have moved the furniture about. He talks about fields and views which are now closed by forest.

Powys and Playter, and their dog (and frequent character in the diary) Black. Photo courtesy of Louise de Bruin.

Given the amount that gardening is mentioned in the diaries, it seems likely that, on a spring day such as this during Powys' time, the flowers also would have been 'popping' in the garden.

Looking north along Harlemville Road, back towards Powys' house. It seems likely that this would not have been a wood-lined way during his day.

The German Graveyard, with stones dating back into the 1800s, is still well-kept and was present in Powys' day. Many of the names whom he mentions as neighbors - such as, Steitz, Krick, Uzner - appear on graves here.

This 19th century stone is inscribed in German. Some of the German settlers around Harlemville may have descended from the 18th century Palatine Germans who were settled in Germantown with the idea that they would help the Livingston collect "navel stores", that is, tar and pitch. When that venture failed, many went elsewhere in the County and the region. Other immigrants arrived at a later date from other regions of Germany.

A mosaic of 1940s aerial photographs showing the land on and around Phudd Hill - regrowth had probably occurred in the 10 years since Powys' residence, however much of the landscape was still open field.

The same rectangle as illustrated for the 1940s but in the year 2009. Extensive reforestation is evident.

With that as an introduction, the remains of this posting are annotated/illustrated spring-time excerpts from Powys’ diaries for the years 1930 and 1931.

Monday 23rd March 1931

…do you know what I saw but I doubt if the Black [‘the Black’ was their dog; a spanialish sort that appears in the pictures] did – in the centre of Phudd Field – The first wood-chuck. It was rearing up so very high on its hind legs and snuffling the air by its hole. I wondered at first whether it were a post but when it dived down I knew it for certain…

[ “Phudd Field” may be what we now call Young’s Field – long the home of many Groundhogs]

The Woodchuck or Groundhog is actually a large member of the squirrel family (something that will seem more intuitive if you ever happen to see one in their occasional forays up trees). While best known for their presence in open fields, they are also found, albeit more rarely, in more wooded situations.

Thursday 26th March 1931

… I looked for long at the water as it rushed round a willow tree and foamed by a rock and whirled along. .. I looked too at the waterfall and red barn and white house with green shutters & old old manure heaps and old wall & posts & water-butt & I thought it is a Ruysdael picture such as … I used to stay and stay to see in Art Gallery in Chicago…

This photograph, while not taken where Powys was standing on the 26th, is from one of his favourite haunts: the Grotto; an area slightly upstream from his house. See more below.

The manure piles are still there, these being across the road from the stream flowing out of the Grotto. Yet, it is hard to know how long they will continue to be there. Farms like this one struggle with a changing market sitution influenced by factors from the local to the international. The high price (and hence high property taxes) of this scenic land so close to NYC, low and fluctuating milk prices, and the difficulties of farming in an increasinly non-farming society are amongst the challenges.

Ruysdael or Ruisdael was an 18th century Dutch illustrator. This work is from the Art Institute of Chicago.

Elsewhere in his diaries, Powys comments on the Red barns of the neighborhood; this one is near the Grotto.

Monday 30th of March 1931

I do so like that little school house… It is the best of all schools – with five children…

[This was probably the building that is now the Banjo Mountain Café.]

Monday April 14th 1930

The tapping beak of the bird woke me at 5:30 AM. Red dawn and white mist and a purple glow to the West. ..a heavy white dew was over all… We have seen the first butterfly! A Camberwell Beauty and heard the sound of the Pheobe Bird and also a bird who said ‘Come, come come and the other girls with you’…

[On Easter, as we made our rounds, a Pheobe was singing across the road from their house. The other bird which he refers to is probably a Song Sparrow. Both of these are native birds of brush and edge.]

"Camberwell Beauty" is the English name for what we call the Mourning Cloak butterfly. This species overwinters as a hibernating adult, and so can appear on just about any warm day of the year. We haven't seen any so far this Spring, this picture was taken during a past year. Because there are so few flowers available when these butterflies first become active, they often rely upon sap running from tree wounds for nutrients..

This Pheobe (photographed a few days after Easter) was perched near the remains of the barn that used to stand on the corner of the main Philmont to Spencertown/Austerlitz road and Harlemville Road, just up the way from the Powys House. The barn was torn down a couple of years ago.

Pheobes are named after their song, a harsh, raspy “Phee-bzee….. Phee-bzee”. Click here for a recording of the above bird’s vocalizations. It was by a busy somewhat busy corner, hence the background noise and the fact that I had to cheat a bit on the sound editing (I was able to record only one good call, so I’ve repeated it three times in this track).

Wednesday 16th April 1930

Got up at 5:30 woken by the tapping of the bird. It is very cold and quite grey today and a north wind with a feel of snow in it. ..There appeared Mr. Steuerwald in his great truck with all our goods. .. And one by one all the things were brought in save the couch and the wicker-chairs which were left on the lawn. Mr. S. is of Herculean proportions. I detected a funny chuckling smile on his face as he drove away like a keeper of a zoo who has just given straw to absurd new beasts from far away.

[The rural/city dichotomy is not new; as Powys’ diary pages amply illustrate there was a regular flow of people between this area and New York City during his time.]

Thursday 16th April 1931

… how sweet the grass smelt! Why do such lovely damp scents rise from the earth at sunset?… the little frogs were very loud in that marshy place beyond the hedge…How green the new grass by that little streamlet…

The bright green of the grass along this "streamlet" near Powys' house is all the more evident for the cloudy weather. Actually, judging by its straightness, this water flow may be an old drainage ditch or, at the least, the recipient of some ardent straightening.

Friday 17th April 1931

Took Black to top of Phudd & saw the Red Sun setting like a great purple plum that you couldn’t eat. Watched as it melted slowly away like a purple heart in the vapour, a plum, a dying heart, a mystery, it faded away.

Saturday 18th April 1931

… Passed the three Ashes and looked for long at the Red blooming Maple near them. Red blossoms are nice to see. There is a little bush with real green leaves [probably Honeysuckle, which, like many other non-native plants, tends to green-up early] coming out there in that mountain glen with swathes of snow-resurrected grass under foot and the silvery river…. I decided to take an extra long walk & I passed the wall-fence of stone & wooden bars…

Male Red Maple flowers. Fireworks.

This illustration, from the 1878 history of Columbia County, shows a solid 'rail-over-rock' fence (together with some other models of fencing). Many of our low stonewalls were surmounted by wooden rails that have now rotted away.

This picture, taken in or near Columbia County, by botanist Rogers McVaugh in 1935, shows a rock wall with decaying rails atop it.

Sunday 19th April 1931

… today near New Bridge I saw the first Blood Root wild… there is one we planted in the Rock garden coming up where those Pansies are out. This morn we saw a White Butterfly [in all likelihood, an early-season Cabbage White – an introduced species that was common by that time and is still common in Harlemville today]….

These Bloodroots were in full bloom on the stone steps of Powys' former house. The current owner says she doesn't think they were planted during her time. During this same Easter walk, we saw many more Bloodroots blooming in their natural, stream-side habitat.

The Cabbage White is an introduced European pest of brassicas (e.g., the cabbage family). It arrived en force during the second half of the 19th century. We haven't seen any yet this year, but they could be about.

Sunday 20th April 1930

…I have begun my Glastonbury Book. May I be inspired by all the spirits of all hills and of all stones upon all hill-sides and upon all plains raised up above sea-level. … Went to the Nymphs Grotto and sat above the waterfall in the twilight….

Pictures from the Grotto; the last perhaps from more or less Powys' above-the-falls perspective.

Monday 20th April 1931

Found the Blood Roots out in our little park. … Two red stalks – one the flower-one the leaf wrapped round in a big grey shawl of the leafy texture & out of this flower comes & a round flower it’s all white and covered up like a white club. As we had breakfast we saw a Phoebe Bird sitting on an old nest on the pillar of our porch… Took Black up Phudd… heard the Hermit Thrush the most beautiful song.

[The Hermit Thrushes, with their haunting songs, still sing from atop Phudd Hill, especially during the last little bit of daylight.]

Wednesday 22nd April

… in the Spinney. Today, however, I found the first Adder Tongue there hence I shall call that wood Adder Tongue Copse… The Willows are out in leaf & on top of Phudd Shad Blow is now out in flower. Red Maples are, here and there, and the Apple Tree (near the pump) is out in green leaf.

[The Adder Tongue are now out. The Shad Blow – aka Shad Bush, Juneberry, Serviceberry – was not in flower on Easter, but made its appearance today.]

The Trout Lilies or, as Powys called them, the "Adders Tongues", are now blooming. Look for groves of their speckled leaves. This one was out along the Agawamuck.

There are several species of native "Shad-Blows" (Amelanchier is the genus), but apparently only one that is tree-sized in our area. Spending most of the year as inconspicuous small trees or bushes, it can be startling to see the white flowers pop out along a fence row. This one sits above a rock ledge near the Banjo Mountain Cafe (and former school house).

Saturday 26th April 1930

…’Twas a perfect day – windless and with heavenly sun – and old rain – drops on every blade, very iridescent. The yellow-brown leaf buds on the distant Maples make a beautiful earth-rainbow under which are green fields and over which distant hills. The calf is grazing happily. The black and white cow is moving about like a prehistoric animal in the dawn of the world… I saw the bowed form of Mrs. Krick gathering medicinal weeds of some kind, perhaps Dandelion leaves, in the meadow. Her form as she bent down was a statue of all women working in early morning under the sun – stoical and in contact with the great old woman and eternal maid the earth.

[Powys was seeing the end of certain traditions, such as medicinal plant collecting – which has returned/continued to some degree – and the middle of others like Holstein-based dairy as a core of the County’s agriculture.]

Not Dandelion but a frequently-confused member of the same plant family. Coltsfoot, like Dandelion, is a European import. One sees it early in the season in disturbed areas such as stream banks and road edges. This cluster was in Easter bloom near the Agawamuck.

Sunday 27th April 1930

… In the afternoon I persuaded the T.T. to visit some hypaticas I had found in the wood in the hill. She got up a blue one, there were also white ones and pinkish ones… Then we went down to the edge of the river for the 1st time but it was cold there but there were Blood roots growing there wrapped up in funnel-like swaddling bands….We saw an extraordinary bird – like a strange waterbird. It was blue and white with a black crest and it flew with the sound of a wooden rattle [Almost certainly a Kingfisher; a bird still to be seen and heard around our waterways].

A particularly purple Hepatica. Although this photograph was taken during a previous year, we have seen Hepatica in bloom this Spring.

Thursday 1st May 1930

…A thunderstorm came and it was followed by warm rain. I walked by the road to Harlemville and got bread.

[Good thing the Farm Store was open…]

For those of you interested in what is perhaps now literature trivia, amongst Powys' nearby friends was the poet Arthur Ficke. He was well-known in his day, but has since faded in renown. This is his former house along Phudd Road. Nearby we heard the deep, thump....thump....thump...thump..thump.thump. thumpthumpthump of a male Ruffed Grouse advertising himself.

It seems appropriate to end this posting with a look back at Phudd Hill on Easter.
