Bird Surveys at Ganondagan SHS, NY



Grassland Bird Surveys at Ganondagan SHS south of Victor, NY (southeast of Rochester) will expand in 2017. Two primary goals of the surveys are to support the designation of Ganondagan as a NYS Bird Conservation Area (BCA) in 2017 and to aid in assessing conservation and habitat-restoration efforts going forward.  Help will be needed and greatly appreciated. Data will be collected using eBird, a free program. ("About eBird" and data-entry instructions for both the free website and free Mobile App are linked at the bottom.*) While grassland birds are emphasized, it's important to record ALL the bird species detected along with their counts or estimated counts. For conservation purposes, we need to know population trends.

For general information on NYS BCA's, go to http://www.dec.ny.gov/animals/30935.html This is a state-level program on state lands, but otherwise it's similar to Audubon's Important Bird Areas (IBA) initiative.

The first 9 survey points (out of 61 planned) are active and can be used by any ebirder. Go to Hotspot Explorer - http://ebird.org/ebird/hotspots - and type in "Ganondagan SHS" and you'll see a list of all the locations. The two general hotspots are always available for any sort of birding at Ganondagan or for birds detected between survey points.

The protocol for the Ganondagan SHS grassland bird surveys, along with maps and sample data sheets, has been revised and can be emailed as a 4-page PDF. Stationary point counts will be 5-7 minutes long depending on habitat. Essentially it's five minutes in open habitat and seven in the more wooded settings. A series or sequence of two or more of the 5-7 minute counts at one point would aid detectability studies for each species reported.

There are five annual target surveys for each point: spring and fall migrations, breeding start and end, and one winter comparison. There is, however, no limit to the number of visits you can make, and ongoing, year-round coverage [weather permitting] would provide the greatest benefit for ornithological research and conservation. Please check the protocol PDF for all reporting details including weather notes and other information to include when using survey points. Non-ebirders can use paper forms or email their results to me at ebirder_14432@yahoo.com and I will forward them to Alexis VanWinkle, Supervising Conservation Steward, Ganondagan State Historic Site, 1488 Rt. 444, Victor, NY, 14564. She is headquartered at the Environmental Field Office, a.k.a. the old visitor center at the top of the hill near the blinking red light. Alexis is "more than willing to host introductory 'meetings' with anyone interested in helping on this project!" You can also contact Dave Spier or Alexis VanWinkle by facebook message.

The annual Allegany Nature Pilgrimage

One of my favorite spring wildflowers, the Pink Lady's-slipper, makes an appearance during the annual Allegany Nature Pilgrimage. Its a beautiful orchid.

It's always a good time to think ahead to spring. Please consider joining us for the next annual Allegany Nature Pilgrimage, the first weekend after Memorial Day, in Allegany State Park, New York. It seems like 48 hours of nearly-nonstop field trips and programs, but they're spread over three days with breaks to eat and sleep. There are early-morning bird walks and bird-banding demonstrations, mid-morning walks and trips, afternoon walks, (or a choice of two all-day trips on Saturday if you prefer), evening walks (beaver and salamanders in the past), evening tent programs with a speaker on Friday and Saturday, followed by after-program frogs, insects and owling. Friday has afternoon and evening walks and events, while Sunday has the morning portion. If I'm not making much sense, just check out their schedule. The new Program Descriptions list was just finalized, and there's a nature walk for every taste, from birds to geology, wildflowers to trees, fields to forests, insects to herps, a bog slog and even specialized programs on photography, dragonflies, bats and beavers. For die-hard birders, there are birding trips from early morning to late into the night plus live birds-of-prey.

Allegany State Park is between Jamestown and Olean in southwestern New York State, next to the Pennsylvania border.

"Old Man's Beard"

Virgin's Bower
© Dave Spier

In the world of plants, there's a vine commonly known as "Old Man's Beard." (Well, that would apply to me, too, but I'm otherwise not green.) It's also called Virgin's Bower and botanists know it as Clematis virginiana, a member of the Anemoneae tribe in the Buttercup Family (Ranunculaceae). The descriptive name refers to the fruit clusters that have seeds ending in long filaments. Other folk names include Devil's Darning Needles and Devil's Hair. The genus name, Clematis, is Ancient Greek for "climbing plant."

The vine is somewhat herbaceous (at least in the north), meaning it dies back to the ground in late fall. It's opposite leaves have three leaflets reminiscent of Poison Ivy, but that is a woody vine. In the spring, Virgin's Bower has to start from scratch. In summer it puts out numerous clusters of small, fragrant flowers, each with four white "petals" (actually sepals). Compared to their colorful and showy garden relatives, they're more inconspicuous.

Virgin's Bower is native to eastern North America. Ours grow in a young woods that's mostly shaded. There they blend in with the other plants. Perhaps in full sun, the vines and flowers would be more noticeable. The vine is capable of climbing trees to a height of 20 feet, but ours just sprawl in a tangled mess across the top of the ground cover and low shrubs. Clematis virginiana tolerates Black Walnuts, which produce chemicals that interfere with some plant's growth. That's a good thing because the squirrels are advancing the walnut forest in that direction.

Giant Swallowtail



© Dave Spier
With a wingspan of roughly five inches (give or take an inch), the Giant Swallowtail (Papilio cresphontes, syn. Heraclides cresphontes) is one of the largest butterflies in eastern and southern North America. Females are larger than males.

This butterfly species ranges from Arizona to the East Coast and from southeastern Canada to Texas and Florida with a population extension into California. In the south the caterpillars are sometimes considered pests in citrus orchards. In the north the larvae eat Prickly-ash (a shrub unrelated to ash trees, although the compound leaves have a similar appearance). Common or Northern Prickly-ash (Zanthoxylum americanum) is in the citrus family (Rutaceae) and sometimes called "toothache tree" because the bark was chewed to relieve tooth-ache. Although I've found prickly-ash locally, its core range is the upper Mid-west.

Giant Swallowtails are dark brown to black with rows of pale yellow spots near the outer edges of all the wings and another row straight across the fore wings. The rear wing "tails" have yellow centers. Small orange and blue spots on the inner wing edges flank the abdomen tip.

Look for these butterflies in open areas and scattered woodlands, a perfect description of our yard where the butterflies check our garden flowers for nectar. The photo, however, was taken beside the Manchester Gateway Trail along Canandaigua Outlet Creek in the Village of Manchester, NY. It was visiting flowers in the open area under the high-voltage power lines. The rest of the trail is mostly wooded floodplain with deciduous trees.

There are several broods per year in the north, but the timing is variable from May to August or September.

European Frogbit

Frogbit

© Dave Spier

Among its many incursions into southeastern Wayne County, New York, European Frogbit (Hydrocharis morsus-ranae) can be found edging Black Creek as it leaves the Montezuma Marshes west of Savannah, just before passing under Route 31 and flowing on its way to Crusoe Creek. This Eurasian species was introduced into Ottawa, Canada in the 1930's and has since spread around the lower Great Lakes and St. Lawrence Seaway watersheds. Its spread northeastward has been limited only by water salinity. There is no limit to the south and west, so it has reached Vermont, New York and Michigan. Frogbit can form dense colonies on the surface and threatens biodiversity by crowding out native species and shading underwater plant growth needed by fish. Its rapid growth also can clog waterways and hinder recreational activities such as boating, canoeing and fishing.
 

Frogbit resembles a miniature waterlily, but its small, pistilate (female) flowers have only 3 petals around a yellow center, unlike the showy native waterlilies with their numerous petals in concentric rows. The frogbit flower resembles those of arrowhead plants, which is not too surprising because both are monocots in the Order Alismatales (although they are in different families). The plant could survive very well without flowers, because its seeds contribute very little to its spread. Instead, the plant can hitch-hike on boats, while its winter buds (called turions) sink to the bottom and lie dormant until spring, when they rise and travel with water currents. The buds grow into complete plants which then enlarge by sending out runners (called stolons) which sprout additional plants in an expanding network that can interlock with adjacent colonies.
 
Frogbit's round, floating leaves (generally two inches or less in diameter), are often notched like water-lilies and grow in rosettes (i.e., radiating from a center point). Dangling roots (to 12 inches long) seldom anchor in the bottom mud, allowing mobility on surface currents, even blowing upstream.

European Frogbit can be distinguished from its native counterpart (Limnobium spongia) by checking the leaf stems. American Frogbit has a midline groove.

Canada Thistle


Beware of tall, attractive wildflowers with prickly leaves growing in fields. Most have beautiful magenta or lavender-colored heads, but the leaves, and sometimes the stems, are edged with numerous, sharp spines to defend against herbivores looking for an easy meal. These are the thistles. They are composites, related to daisies and goldenrods in spite of the obvious differences. Most are biennials, starting as a ground-hugging rosette of prickly leaves the first year, then growing tall and flowering the second.
 

The Canada Thistle (Cirsium arvense), a misnamed alien invasive from Europe, is one of the less-obvious species here [in the northern Finger Lakes region of NY] because its light-purple heads are less than an inch high. The whole plant grows four to five-plus feet high and often forms dense colonies after spreading by underground stems. In Europe and northern Asia, it is known as Creeping Thistle. One plant's roots can spread to a three-foot diameter (or more) in one year and continue growing at this rate for many years, making it a difficult plant to eradicate. A single thistle plant can be considered biennial, but the root system is perennial and continues to put its energy into new clonal [cloned] shoots.
 
Canada Thistles form colonies from a spreading underground
 root system. Less energy goes into producing flowers.
Less energy goes into producing flowers which are usually dioecious (either male or female). Male flowers may be slightly smaller, but otherwise similar. Both are very fragrant, which is energy spent to attract pollinators and NOT humans. Female flowers produce 40 to 80 seeds per head, but the fuzzy pappus is loosely attached and often ineffective in seed dispersal.

Canada Thistle's main stems are smooth, but the deeply-lobed leaves are designed to keep you at a distance. In the spring, wear heavy gloves and protective clothing so you can return to the location and collect the young leaves, young stems and roots for food. One of the plant's nicknames is "lettuce from hell" (and it actually is related to lettuce). After removing the spines, add young leaves to salads or eat them cooked. The pithy, young stems are easier to deal with; just peel and eat raw or cooked. The roots of first year plants, before the tall stems begin, are a survival food, but they also can cause flatulence.

A crab spider is camouflaged against a Canada Thistle flower bud.

Canada Thistle is also food for wildlife, especially goldfinches and other finches that eat the seeds. Some butterfly and moth larvae eat the leaves. Look for Red Admirals, Viceroys and Painted Ladies on this thistle. The larvae of the Orellia ruficauda fruit fly parasitize the fertile seed heads, making them a somewhat-effective biological control.

In the past, a tea made from the leaves was used as a general tonic (stimulant) and diuretic to increase the loss of water from the body. Externally, it was used for skin sores and poison-ivy rash. Native Americans used a root tea as a digestive tract stimulant and dewormer. (I wonder what they used before Europeans introduced this wildflower.) At the other extreme, it was said to cause inflammation and irritation (Jacobs and Burlage). Go figure.
 


Cirsium comes from the Greek word, kirsion, from kirsos, a "swollen vein" remedied by one of the species in that genus. The species name, arvense, is Latin for "in the field." Among its other common names are "field thistle," "perennial thistle" and "cursed thistle." It was originally native to the Mediterranean and southeast Europe and likely arrived in North America during the 1600's.

Black Raspberries

Yummy

I have mixed feelings about early July. On the down side are the humidity and the mosquitos (which seem to have reached a new peak). On the positive side, the wild Black Raspberries are ripe. For years, I've been encouraging these bushes to grow around the perimeter of our property. Even though they're thorny and often hook me on the arm or in the hair, the rewards seem to be worth it.

Black Raspberries are native to eastern North America.

The common species is Rubus occidentalis, but similar varieties are numerous. They belong to the rose family, making them direct relatives of blackberries, strawberries, rose hips, cherries, plums, apples and pears. They are nicknamed "black caps" or "thimbleberries," referring to the way the ripe fruit separates easily from the pedicel leaving a round button called a carpel or receptacle (which seems misleading). True blackberries, a distinctly-different species, do not separate from the receptacle. Individual raspberry fruits are composite clusters of small beads called drupelets, each containing a tiny seed. The dark-purple color is produced by anthocyanin pigments which makes them useful as natural dyes -- witness the color of your fingers after picking a few. Raspberries are also healthy. The anthocyanins are powerful antioxidants and are being tested for their effect on cancer.
 
Raspberry canes have a whitish, powdery bloom, best seen at upper left
It takes raspberry canes a year and a half to mature and bear fruit. The first year, the canes (green with a whitish, powdery coating) bear compound leaves usually with three leaflets but sometimes five arranged palmately (like fingers or spokes from a single point). The undersides of the toothed leaflets are silvery white, much like Silver Maple leaves. The second year, the canes turn dark purple or reddish, but the remaining powder makes them look bluish. They send out short branches that produce alternate, compound leaves with only three leaflets (unfortunately resembling poison ivy). Flowers with five white petals appear in May and these develop into red fruits which turn dark as they ripen around July 4th, give or take, here in the Finger Lakes region of New York. After the fruit is gone, you can still use the leaves to make tea.

The undersides of Black Raspberry leaves [turned over at right] are nearly white.

The arching canes may root at the tip if they touch the ground. In this way, one shrub can form broad colonies that provide protective cover for small mammals. During the winter, the canes of all brambles (including dewberries, black and red raspberries and true blackberries) become food for cottontail rabbits. Canes die at the end of their second year, but the roots continue to send up new shoots every spring.

Black Raspberries are native from Wyoming to Ontario and Quebec and south to Georgia and Mississippi. If you live in this area and want to collect raspberries, you need to get to them before the songbirds, game birds and wild mammals of all sizes. If you want to grow your own, they tolerate a wide variety of conditions from open sunlight to shade and soils that are moist or dry. They will grow in open woods, thickets, stream banks, wet meadows and old fields as well as the edge of your lawn. If you leave a spot around some trees unmowed, the birds will probably drop some seeds and help you get started. In two years you'll be on your way to healthy eating.

Black Elderberry

Elder usually has seven sharply-toothed leaflets,
but the number can vary from five to 11.
© Dave Spier

Common Elder, a.k.a. Black Elderberry (Sambucus canadensis, syn. Sambucus nigra, ssp. canadensis) is a native member of the Honeysuckle family. Beyond the opposite, pinnately-compound leaves, there's little resemblence to indicate the relationship. 

Numerous, small, white flowers are crowded into flat-topped terminal disks that are conspicuous in late June and early July in New York. The flower clusters can be dipped in batter and deep-fried like fritters, or wait for the dark-purple, juicy berries to ripen and make a pie. The dark fruits give the shrub it's alternate name, American Black Elderberry. Aside from the mentioned edibility, take note that the leaves, twigs, roots and unripe fruit are toxic due to cyanogenic glycoside and alkaloid.

The woody stems contain white pith that can be removed in order to make a flute or whistle. This musical quality is the basis of the genus name; in ancient Greece, sambuce was a musical instrument. Given the toxicity of the stems, though, I'd rethink this use for the plant.

Common Elder's range spans all of the southern states from California to Florida, north across most of the Lower 48 (except the Great Basin and Pacific Northwest) and continues north into eastern Canada. There's a range map on the USDA Plants Database. Many of the states have more detailed maps down to the county level. For example, the opening photo was taken at Newtown Battlefield State Park, near Elmira, NY, but the shrub occurs in other scattered locations across New York State.

This elderberry seems to require more sunlight than it's woodland cousin the Red-berried Elder, so look for the purple-fruited species on the edge of woods, usually in lowland spots where there is extra soil moisture, although I would not describe it as a true wetland species because of its low anaerobic tolerance. We live on top of a drumlin ridge and a Common Elder has "volunteered" to grow behind the garage where it is somewhat sunny, at least part of the day. We can assume the original seed was dropped by a bird. A number of species including robins, catbirds and waxwings are berry eaters. I'd be interested in knowing whether elderberry grows near you.

Dame's Rocket


Dame’s Rocket (Hesperis matronalis) is another invasive alien, albeit an attractive one, in the mustard family. It is now widespread along roadsides, woods edges and damp thickets, but it started as a garden escape after it was introduced from Eurasia. (There's a range map on the USDA Plants Database.) Many years ago, we tried growing it on our dry hilltop, but it never took hold (probably a good thing in retro-spect), so look for it in lower areas with partial shade. It seems to prefer moist soil but avoids true wetlands.  As an example, at the Montezuma Audubon Center, it grows throughout the walnut grove and around the edges, but it’s generally absent from the open fields.


Also known as Purple Rocket, this biennial or short-lived perennial herb comes in a range of colors from pale lavender to hot pink and purple. All of the blossoms on an individual plant are usually the same color, but adjacent plants may vary widely. Light and dark colors are often mixed together in the same vicinity and sometimes you’ll find flowers with white streaks on purple petals. Rarely, several colors are mixed on the same flower. The four petals make an “X” or cross, which is characteristic of the mustards (the Brassicaceae, formerly Cruciferae). At first glance it resembles Phlox, but Phlox has five petals (the same as the number of letters in its name).

The purple variety of Dame’s Rocket generally produces more seeds per plant and seems to be the dominant color. The stalked seed pods are thin and erect and split open when ripe. The plant usually grows several feet tall. The lance-shaped leaves are long-pointed, toothed along the margins and they alternate (i.e., are not opposite) along the hairy main stem below the flower and seed clusters.

The best time to enjoy this plant may be when it’s backlit by the afternoon sun. In the evening it gives off a lovely fragrance, probably timed to specific pollinators that rest during the day. This is reflected in another common name for the plant, the night-scented gilliflower. The scientific genus name, Hesperis, is Greek for evening.

Celandine

© Dave Spier

Celandine, Chelidonium majus, is a somewhat invasive alien with attractive yellow flowers arranged in an umbel (think inside-out umbrella), although the blossoms tend to open one at a time. Each showy flower has four petals. Black seeds growing in long capsules continue the superficial resemblance to mustards, but Celandine is actually in the Poppy family, although it's different than Celandine Poppy, a more Western native species. Celandine's somewhat grayish-green, compound leaves are irregularly lobed and scallop-edged.

This species is often called Greater Celandine to distinguish it from Lesser Celandine, Ranunculus ficaria, a quite different plant in the Buttercup family.

You can find a range map on the USDA plants database website. Celandine is widespread in the Midwest, Northeast, Eastern Canada plus outlier states like GA, NE, UT, MT, WA and adjacent BC. Clicking on some of the states will give you more refined maps down to the county level. For example, clicking NY will show Celandine's distribution across the Finger Lakes. It appears to be missing from Schuyler County, but I have photographed it in Wayne County, so that omission is an error.

When broken, Celandine's stems exude a somewhat-poisonous yellow latex that can cause dermatitis or eye irritation in sensitive individuals. A final note of warning -- Celandine is toxic due to a range of isoquinoline alkaloids so avoid ingesting the plant, and wear protection if you're pulling the plant to remove it.

Rhododendron



Great Rhododendrons (Rhododendron maximum) grow wild in scattered colonies across New York and New England as far as southwestern Maine, but it's found primarily in the Appalachians from Pennsylvania to northern Georgia. Beyond that it has been widely planted as an ornamental. Wherever there is sufficient moisture, these evergreen members of the heath family can form dense thickets generally reaching a height of 13 feet, but old bushes are capable of growing to a height of 30 or even 40 feet and a crown diameter of 12 feet, essentially becoming small trees. The main requirement is acidic soil with a high organic content.

The concave leaves are long and leathery and curve down to smooth edges that may curl under during dry or cold weather. Most of the leaves are clustered in whorls around the end of twigs and surround the showy, rose-pink to purple, sometimes white, flower clusters that open between March and August, depending on the local climate. Our ornamental version opens in late May here in the northern Finger Lakes region.


In the wild, rhododendron is an understory plant and does well in the shade of taller trees. Combine that factor with the shrub's dense, evergreen foliage and you can understand why it's difficult for smaller plants and wildflowers to grow underneath rhododendrons.

This species has a number of alternate common names including Late or Summer Rhododendron, Great, Bigleaf or Deertongue Laurel and Rosebay. It's the state flower of West Virginia. The name Mountain Laurel is reserved for its smaller relative, Kalmia latifolia.

Shagbark Hickory

emerging hickory leaves can sometimes resemble praying hands
 © Dave Spier

A week of warm weather has created a green paradise in the northern Finger Lakes region of New York. Among the many transformed deciduous trees, the Shagbark Hickory (Carya ovata) leaves have emerged. When the giant bud scales first peeled open, the "fingers" of miniature leaves resembled "praying hands." Once fully opened, the hickory's feather-compound leaves become distinctive. There are five (sometimes seven) leaflets with four opposite and one at the tip. The smallest are the inner, the middle pair are larger and the terminal leaflet is the largest. All are toothed and long-pointed. By the time it's done growing, a compound leaf can reach over a foot in length.

Shagbarks, aptly named for the long, peeling shreds of bark, can easily grow to a height of 60 to 90 feet. The record is 120 feet. The wood is strong and elastic and was once prized for tool handles, gunstocks, skis and chair backs. When burned, it gives off a lot of heat and makes high-grade charcoal.

Shagbark Hickory bark
In late summer and early fall, the thick-walled nut husks split into four sections and release the four-ridged nuts which are good to eat. (Squirrels, possums, Wild Turkeys and Wood Ducks would agree.) The nuts also can be ground in a meal-like flour or crushed and boiled to separate the oil. Rabbits and deer browse the twigs. In late winter, the trunks can be tapped in the manner of collecting maple sap.

Hickories are related to walnuts and butternuts (Juglans spp.) which have numerous leaflets, all roughly the same size. All these trees are in the same family (Juglandaceae) along with pecans.

Wild Geraniums


A true member of the Geranium family, the wild variety has small clusters of flowers with five showy, rose-pink petals. After the petals fall, a long "beak" remains and gives geraniums the nickname "cranesbill." The Greek word for crane is geranos, which is the root of our common name, geranium. The wild one is also called spotted crane flower, but the reason for "spotted" eludes me.

Growing one to two feet tall, Wild Geraniums (Geranium maculatum) are found in woods and shady roadsides, often near streams, from Maine to Georgia and west to Arkansas and Manitoba. The attractive, soft-green, hairy leaves are deeply divided into five (sometimes 3-7) radial lobes reminiscent of Silver Maple leaves.

The roots are rich in tannin and were once used in folk medicine to treat a variety of ailments. This earned the plant the name astringent-root.
With attractive flowers that are 1-1.5 inches in diameter, the plant rates a place in ornamental gardens. Wild Geraniums are now available commercially, as are many native wildflowers.

Dandelions




Can't Beat 'Em? - Eat 'Em!

What's your opinion of dandelions? Consider this: the young leaves (before the flowers appear) are edible, assuming you don't use pesticides or other chemicals on your lawn. The leaves grow in a rosette like the spokes of a wheel and average 20 per cluster. A large root system can support a double head that appears to have 40 leaves. The individual leaves are long and pointed, sometimes like an arrowhead at the tip, and coarsely toothed along both sides. The jagged teeth are often reflexed and may even point toward the center of the plant. Long ago, someone thought they resembled the teeth of a lion. In French, the name was "dent de lion" which morphed into dandelion. Other common names for this plant include blowball (a reference to the globular seed heads), lion's-tooth, wild-endive, priest's-crown and Irish-daisy.

The Common Dandelion (Taraxacum officinale) is a member of the Daisy family, also known as the Aster family and sometimes the Composite family. The complex flower head is a composite of numerous yellow rays designed to attract insects and a central disk of florets that produce the seeds. In exchange for transporting pollen, the blossom rewards insects with nectar. Bumblebees, butterflies and a host of other arthropods visit the radially symmetrical heads. What insects have you seen on dandelions?

Garden lettuce, Lactuca sativa, is a distant relative in the same family so it might be no surprise that dandelions are also food for people. Collect the young leaves and add them to a salad. They are rich in vitamins A, C and E plus iron, potassium and calcium. Slightly older leaves can be boiled to remove any developing bitterness and eaten like spinach. Young flower buds, still tucked down in the rosette of leaves, can be boiled and served with butter or they can be pickled. The buds can also be added to soups, stews and pasta dishes. The yellow flowers can be dipped in batter and fried like fritters. [A word of caution: the hollow flower stalks contain a white, milky latex that can irritate sensitive skin.] The heavy taproots can be slow-baked until brown and brittle, then ground and used like coffee in the manner of Chicory, another Composite. During the Great Depression, dandelions were an important part of the diet for many people. Likewise, in World War II, European country folk nearly eradicated this plant. Dandelions are native to Europe and were originally brought to this country for their food and medicinal value. Some homeowners would like to send these invasive aliens back.

Common Dandelion leaf and blossom

Worldwide there are about 60 species of dandelions. Many can reproduce asexually, meaning they are capable of cloning seeds without pollination. These populations are found in northern latitudes where they are presumably remnants of the Ice Age when insects may have been in short supply.

Regardless of how they are produced, the dandelion has a very effective seed dispersal system. After pollination (or cloning, as the case may be), the yellow flower head temporarily closes, then opens into an almost white ball of fluff. Each seed comes with its own parachute and the next wind will carry it on its way. A number of birds eat the seeds, and I would guess the goldfinch is among them, given the finch's fondness for thistle seed (still another member of the Composite family). Has anyone counted the number of seeds produced on one head?

Once established, the dandelion plant keeps its leaves flat to the ground, shading out anything beneath them while avoiding your mower blades above. Like any number of other plants, including certain ferns and garlic mustard, the dandelion emits chemicals that inhibit the growth of nearby vegetation, usually grass. The deep taproot resists attempts to pull the plant becasue it breaks near the surface and then grows a new rosette of leaves and new blossoms. The month of May is the peak flowering month in New York, but sporadic blossoms appear throughout the summer and late into fall, weather permitting.

If you can't admire the dandelion as a prolific survivor, then at least save your money and eat it. Given the rising cost of food, that's not a bad idea.
