One of the earliest flowers to bloom: here, usually in late March or early April, much earlier than any spring ephemerals native to Minnesota. So wonderful to see the golden flowers against the dreary gray and brown carpet of fallen leaves and twigs. So far I have three clumps and many immature plants under a hazel bush. They grow and go dormant before the bush develops its leaves. First a flower above a whorl of small bronze leaves. Then the flowers wither and the leaves expand and get greener while the seed ripens. Finally, the capsules dry and split open to reveal hard brown seeds, and the leaves go dormant for the summer.

Valuable source of nectar and pollen if warm enough for honey bees to be out while in bloom

These have naturalized at the CNC and some drifts are 40' across.
