Blue Cohosh, Squaw-root, Papoose-root, Caulophylle Faux-Pigamon
Valued for its attractive foliage and ornamental blue berries, Caulophyllum thalictroides (Blue Cohosh) is an elegant, rhizomatous perennial with lacy, refined, blue-green leaves divided into three leaflets. The emerging stems and leaves boast purplish highlights. In mid to late spring, sprays of inconspicuous, green or yellow-brown, star-shaped flowers, 1/2 in. (1 cm), appear above the foliage. The petals bear fleshy nectar glands that are visited by early solitary bees. They are followed in summer by erect clusters of showy, bright blue, berry-like seeds. They persist and provide early fall interest even after the foliage has declined. Easy to grow, requiring minimum care, and long-lived, Blue Cohosh does best in shady woodland areas with humus-rich slightly acidic soil.
