Description: Dutchman’s Breeches is a distinct plant that gets its name from the flowers that dangle down. The flowers resemble pantaloons hanging upside down and slightly inflated. They bloom April to May, are approximately ¾ inch in length, and white to pinkish in color with a yellow line at the bottom of the flower (representing the belt on the pantaloons). Four to ten flowers hang from a stalk measuring five to ten inches long. The leaves grow at the base, and are ternatly divided and segmented greatly. The underside of the leaves are a paler color than on top. Once the forest canopy encloses and blocks all sunlight, the plant will stop blooming. Soon after flowering and by mid-summer, the leaves will turn yellow and disappear. The flower stalks and leaves arise from a underground scaly bulb. Seeds are dispersed by ants, who are enticed to carry the seeds underground because the seeds contain Elaisome, a favorite to many ant species (Biology, the science of Life, BIOL 103 CD-ROM telecourse, 2005). The fruit is a two-part capsule, pollinated by bumble bees whose proboscises are long enough to reach the nectar. Honey bees pollinate by their front feet. Other insect species that can not reach the nectar will snip a hole at the bottom of the flower to “steal” it of nectar (Thieret, Niering, & Olmstead, 2005).
Habitat: Southeast Canada to Georgia, over to Arkansas, Oklahoma and North Dakota (Foster & Duke, 1977)
It grows in rich woods and on rocky slopes, up to 5,200 feet in elevation (Stukham, 2001). They are found on North to Northeastern slopes.
In Shenandoah National Park, it can be found in lower to middle elevations, on Northern slopes, East of Skyline Drive. They have been seen in areas such as White Oak, and Upper Dark Hollow Falls. Many can be found near trout lily, and spring beauty (Interview: Mara Meisel, 2005).
Common Names:
Soldier cap, white hearts, eardrops, monks head, butterfly banners, kitten breeches, bachelors breeches, little boys breeches, and staggerweed (Wisconsin Cooperative Educational Service Agency, Toxic Plant Database, Veterinary Medicine, Perdue University).
Other Facts:
The plant contains several isoquinoline alkaloids, including aporphine and protopine (found in opium poppies), all of which are poisonous (Adkins, 2005). These alkaloid are a central nervous system (CNS) depressant, which can cause paralysis and tremors.
Eating the leaves and roots can cause poisoning, similar to bleeding heart. The symptoms include a staggering gait or walk, which gives it one of its common names (staggerweed). Cattle and horse feed on this plant during spring grazing, causing sudden trembling which increase in severity, frothing of the mouth, ejection of partially digested stomach contents, and convulsions. (University of Illinois – Urbana, Veterinary Medicine Toxic Plant website, 2005).
The Iroquois used leaf ointment to create more limber legs on athletes. Leaf poultice is used for skin ailments, and the root turned into a tea becomes a diuretic, which promotes sweating (Foster, Steven, & Duke, 1977).
