Blue Cohosh (Caulophyllum thalictroides) is a choice woodland wildflower treasured for its lacy blue-green foliage and deep blue berries. This beautiful shade garden plant prefers a soil with abundant organic matter from decaying leaves and consistent moisture. A cluster of yellow flowers appears at the branching "Y" of the stem in spring, and gives way to the berries that eventually turn blue. The berries are slightly toxic for humans, and should not be eaten. Late season foliage turns bright green-gold. Combine this shade-loving species with lower growing wildflowers and sedges. Once established at a favorable site, Blue Cohosh is a long-lived plant.
