Dense, 10 in. high masses of deeply cut, fern-like leaves subtend a naked flower stalk bearing a row of nodding, double-spurred, white flowers. Clusters of fragrant, white, pantaloon-shaped flowers are on a leafless stalk and overtop the much-divided, feathery basal leaves. This woodland perennial can spread to cover considerable areas.
The generic name of this delicate spring ephemeral flower derives from the Greek for two-spurred. The flowers are pollinated by early bumblebees, whose proboscis is long enough to tap the nectar. Honeybees, with a shorter proboscis, can gather only the pollen with their front feet. Squirrel Corn (D. canadensis), closely related to Dutchmans Breeches, is often found in the same habitats. Its flowers, however, are heart-shaped. The root tubers resemblance to corn kernels accounts for its common name. The plant goes dormant in early summer.
