Winter Aconite - Eranthis hyemalis (spring ephemeral)
Winter Aconite is not native to Wisconsin or North America but it can naturalize under the the right conditions. A member of the buttercup family (Ranunculaceae) is one of the earliest bulbs to bloom in spring.
Native to Asia Minor and Europe, Winter Aconite grows 3-6″ tall.
Hyemalis: Latin for "winter-flowering".
Er: Greek for "Spring" and anthos: Greek for "flower" - so named for its early flowering
