Anemone canadensis (Canada anemone, round-headed anemone, meadow anemone, crowfoot) is a herbaceous perennial native to moist meadows, thickets, streambanks, and lakeshores in North America, spreading rapidly by underground rhizomes, valued for its white flowers.
Shoots with deeply divided and toothed basal leaves grow from caudices on long, thin rhizomes.
Flowers with about 5 sepals and numerous stamens bloom from late spring to summer on stems above a cluster of leaves.
Seeds are achenes, borne in a small dense head.
In former times it was used medically by North American Indigenous peoples as an astringent and as a styptic for wounds, sores, nosebleeds, and as an eyewash. The root was respected by Plains tribes and used for many ailments.
It is likely that most Anemones contain the caustic irritants of the Ranunculaceae family.
