Anemones don't have real petals, but have sepals which look like petals. This flower has four (also five) obovate-oblong sepals, which makes it look like clematis. It is a robust perennial with erect hairy stems growing up to 1-2.5 ft. Basal leaves a heart or kidney shaped, deeply 5-lobed, on long stalks. Stem leaves, just below the flowers are stalkless, lobed, but much smaller than basal leaves. White flowers occur in umbels of 6-15 flowers.
