Native to the Finger Lakes Region
A non-native plant with very early yellow flowers and fringed foliage. Spreads aggressively.
Light: sun to shade
Moisture and Soil: dry to moist soil
Seed Treatment and Storage: warm/moist then cold/moist stratification
Haudenosaunee runners made a compound infusion of the leaves and used it as a liniment to strengthen their limbs. It has even been reported that young men would chew the roots to attract women.

Queen bumble bees pry open the complex flowers and feed on the nectar with long tongues, picking up and transferring pollen along the way. Dutchman's breeches can self pollinate if queen bumble bees are absent. Worker bees and cuckoo bees (Nomada spp.) bypass the flower opening and feed on nectar through perforations in the spurs. Dutchman's breeches seeds are ant-dispersed. Herbivores avoid the toxic foliage.
Climate change sensitivity
Over the period from 1986 to 2015, Eranthis hyemalis bloomed an average of 18.5 days later.
Like its relative squirrel corn (Dicentra canadensis), all parts of dutchman’s breeches are poisonous to cats, cattle, and humans because it synthesizes the neurotoxic alkaloid isoquinoline. The underground tubers have been found to cause convulsions in cattle.
This wildflower has tiny underground tubers that look like kernels of reddish corn. Insect pollinators often make holes in the base of its spurred flowers to "rob" nectar.
