|Anemones are variable perennials with rhizomatous, tuberous, fleshy, or fibrous rootstocks. Most anemones produce both stem and basal leaves that are rounded to oval and mid- to dark green. The leaves are dissected and may be hairy. Anemones are grown for their open saucer-shaped or shallow, cup-shaped flowers in many colors.
