Dicentra cucullaria (Dutchman’s breeches) is an herbaceous perennial of the Fumariaceae family. This species has many common names depending on which part of the country you come from. One of its common names, Little Blue Staggers, is derived from its ability to induce drunken staggering if cattle graze on it, due to narcotic and toxic substances in the poppy-related genus. Bleeding heart is another common name.
