Anemone virginiana is an upright growing herbaceous species of flowering plant in the buttercup family Ranunculaceae. It is a perennial that grows 30–80 centimetres (12–31 in) tall, flowering from May until July. The flowers are white or greenish-white. After flowering, the fruits are produced in dense rounded thimble-shaped spikes 15–35 millimetres (0.59–1.38 in) long and 12 millimetres (0.47 in) wide. When the fruits, called achenes, are ripe they have gray-white colored, densely woolly styles, that allow them to blow away in the wind. The leaf structure is whorled halfway up the stem and each individual leaf appears to be deeply cut.
