|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.
'Blue Bonnet' is a short, creeping, vigorous, rhizomatous perennial with 2 to 5 inch long, 3-palmately compound stem and basal leaves. The leaflets are narrow, toothed, and divided even further. Small, 1 1/4 to 1 1/2 inch wide flowers are borne in late spring. Foliage dies back shortly after blooming. Native to Europe.
