Discussion

Eranthis hyemalis is a garden plant that sometimes persists after cultivation and occasionally becomes established locally. It has been reported for Newfoundland but it is probably not established there.

Eranthis cilicicus from southeastern Turkey, usually with more leaflets and smaller flowers, may be distinguished from E. hyemalis in gardens but not in the wild. Hybrids between the two species are referred to as E. ×tubergenii.
