THE WILD CARROT
For one, the plant is amazingly abundant, growing in old fields and even along roadsides where more fastidious flora can't survive. Second, its root is darned tasty (sort of). And third, as the Wild Carrot's more familiar name indicates, it's not even a native plant. We're talking here about Queen Anne's Lace, an Old World import that found much of the rest of the globe to its liking when its seeds were introduced by settlers from Europe. All text & photos © Hilton Pond Center Indeed, Queen Anne's Lace is so adaptable that in some habitats it's an invasive plant, crowding out native species that can't compete with its vigorous growth. No doubt about it, however, this foreign invader is eye-pleasing, with white umbrella-shaped flower heads that form at the end of three-foot-tall stalks. Whether viewed from the side (above) or from directly overhead (below), we find the three-inch-wide inflorescence is actually a bunch of individual clusters that radiate from the vegetative stalk and that themselves consist of 20 or more individual flowers--each only an eighth of an inch in diameter. Despite its origins, Queen Anne's Lace is a pretty interesting plant for North American botanists. It takes its common name from a British monarch who was adept at lace-making, and the plant's flower certainly is lace-like, resembling an old-fashioned doily. Curiously, at the center of some Queen Anne's Lace flower heads there is a floret that is deep red-purple rather than white (above). No one knows for sure what the function of this special structure might be, but English tradition says it is a drop of blood that fell from Anne's finger when she pricked it making lace. Perhaps this unusually colored flower part (magnified below) serves as a target for potential pollinators.
Queen Anne's Lace is in the Apiaceae (Parsley Family), along with a number of other aromatic plants that have been used as spices or foods: Caraway, Fennel, Coriander, Anise-Root, Celery, and--of course--Parsley. The deadly Poison Hemlock is also a relative. Many of these plants have lacy, fern-like leaves, but even those of Queen Anne's Lace are highly variable; the coarse form is pictured below left. Most of the Apiaceae also have deep tap roots that provide nutrient storage areas. The scientific epithet for Queen Anne's Lace is Daucus carota. "Carrot" comes from a Celtic word for "red," while Daucus appears to be derived from the Greek dais, which means "to burn" and pertains to the strongly pungent taste and odor of both wild and domesticated carrots. Admittedly, the root of Queen Anne's Lace is much more bitter than the sweet-tasting carrot from your local grocery, but there's no denying the basic similarity. Incidentally, Daucus carota does have a native congener--D. pusillus--that grows in the western U.S. and eastward along the Gulf Coast states to Florida. The species resembles Queen Anne's Lace but has fewer florets per flower cluster (5-12 instead of 20-plus); it is a good non-invasive pollinator plant for backyard habitats. Although Queen Anne's Lace can be invasive, its introduction may have been a boon for Eastern Black Swallowtail butterflies, whose caterpillars eat the leaves. Queen Anne's Lace is a biennial--a plant that, in this case, germinates from seed and spends its first year developing basal leaves and a tap root. In the second year it sends up a flower stalk, produces blooms, sets seed, and then dies. The seed head of Queen Anne's Lace is as interesting as its flowers. After pollination occurs--often at the service of miniature flower beetles that roll and tumble among the myriad blossoms--the umbel of the flower head begins to fold in on itself, rather like an umbrella turned inside out (below). When number two son Garry came across these structures on trails around Hilton Pond, he always called them "bird nests"--which the seed heads do indeed resemble. A close look at the seed head reveals how it can be that Queen Anne's Lace is so prolific. At the tip of nearly every tiny flower stalk is an equally minute ovoid fruit covered with even tinier sharp bristles. The seeds on the plant in these photos are still a tad green, but by summer's end they'll be brown and dry and ready to latch onto the fur of some passing mammal--an unknowing disseminator that will help start a new biennial generation of edible Wild Carrots at Hilton Pond Center.
