The Canada anemone has shoots with deeply divided and toothed basal leaves on 8–22 cm . They grow from ascending caudices on long, thin rhizomes. The shoots are 20–80 cm tall, and leaves are 4–10 cm by 5–15 cm .Flowers with about 5 white, petal-like sepals and 80-100 yellow stamens bloom from late spring to summer on stems above a cluster of leaves. The sepals are obovate and 10–20 mm by 5–15 mm .
When they are pollinated, the green pistils in the middle of the flower become a rounded to slightly lengthened seed head. The seeds are achenes, with an almost round body and a beak.
