The Wood Anemone is a member of the Buttercup Family. The flower is approximately 1″ in diameter,white and sometimes pink on the reverse side.

Anemone quinquefolia is an early-spring flowering plant in the genus Anemone, native to North America. It is commonly called Wood Anemone, like Anemone nemorosa, a closely related European species. The American species has been treated as a subspecies of Anemone nemorosa.

It is a perennial herbaceous plant, growing in early spring to 10–30 centimetres (3.9–11.8 in) tall, and dying back down to the root-like rhizomes by mid summer. The rhizomes, that spread just below the earth surface, grow quickly, contributing to its rapid spread in woodland conditions, where it can carpet large areas. The flower is 1–2.5 centimetres (0.39–0.98 in) diameter, with five (occasionally four, or six to nine) petal-like segments (actually tepals). The flowers are white, commonly flushed pinkish.

The leaves are in three parts with deeply lobed lateral leaflets, giving the appearance of five leaflets. The leaf veins are branched and not parallel.—Wikipedia
