A spring ephemeral with small white flowers and lovely compound leaves, native to the east-central United States and the southern tip of Ontario. Easy to confuse with Rue Anemone (Thalictrum thalictroides) and Wood anemone (Anemone quinquefolia) . Unlike them, it spreads gradually each year by underground rhizomes to form a closely spaced clump.

Basal leaves emerge in the fall, last through the winter, then go dormant along with the flower stems in summer.

Like many plants in the buttercup family, it only produces pollen. Medium to small bees visit it to gather the pollen for their nests (the flowers are too small to provide enough pollen for bumblebees and the stems too delicate to support them), and hoverflies eat the pollen.
