Usually called Canada Anemone, but also called Round-headed Anemone, Round-headed Thimbleweed, and Canada Crowfoot. It is native to damp meadows and fields and shores of watercourses and lakes from southeastern Quebec to southern British Columbia, down to Virginia over to spots in the mountains of New Mexico & Colorado. The leaves surround the stem as stalkless or sessile. The seed-like or thimble-like fruits are not hairy or only sparsely hairy and the seedhead is rounded and about as wide as tall. it has 5 white petal-like sepals with 80 to 100 yellow stamens and some green pistils in the center of the flower. The seeds are achenes (sunflower-like seeds). Prairie moon Nursery, a native plant nursery in Winona, Minnesota, recommends that it is a great groundcover to replace the European Common Periwinkle (Vinca minor) with pretty foliage even when it is not blooming. It spreads rapidly by rhizomes and can be aggressive in a conventional garden. In a conventional garden if the plants become too crowded and bloom less, the plants can be divided in the fall to reset them. All parts of the plant are toxic if eaten.

Canada Anemone ranges naturally from the central southeastern states west to Nebraska and northward into Canada where it prefers low open fertile woods and damp meadows. It has basal, bright green, deeply cut leaves which resemble those of hardy Geranium, and flowers on slender 1 to 2 foot tall stalks in early summer. The 1 inch, daisy-like flowers are held singly and delicately. This Anemone can grow rampantly in part shade in moist, good soil and could be used to cover large areas. In part shade, growth will be slower.
