Blue Cohosh prefers medium to moist soils and grows well in partial to full shade making it an ideal choice for a shade garden. Blue Cohosh blooms in early spring, producing small, greenish-yellow flowers that attract pollinators. Later in the season Blue Cohosh produces striking blue-purple berries that are consumed by small mammals although they are toxic if consumed by humans. Blue Cohosh is also the host plant for the Celastrina neglectamajor butterfly.
