Dicentra cucullaria - Dutchman's breeches
Dicentra cucullaria (Dutchman's breeches) is a flowering plant in the family Fumariaceae, native to North America. It occurs mainly in the eastern half of the continent, from Nova Scotia and southern Quebec west to eastern North Dakota, and south to northern Georgia and eastern Oklahoma; there is also a disjunct population in Idaho, Oregon and Washington. It typically grows in rich woods. The common name Dutchman's breeches derives from their white flowers that look like white breeches.
