Caulophyllum robustum - Blue Cohosh - 4 Seed Pack - Exotic Perennial Flowering Shrub - New

Caulophyllum is a small genus of perennial herbs in the family Berberidaceae. It is native to eastern Asia and eastern North America. These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer. Common names for plants in this genus include Blue Cohosh, Squaw Root, and Papoose Root.

As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.

Caulophyllum robustum commonly known as Blue Cohosh is a Russian and Eastern Asian species, good for the woodland garden in moisture retentive soils, long lived and attractive but slow growing. Germination will be spread-out over 4 years after the initial conditions of cool/moist treatment have been completed. Sow outside in a sheltered location with the seeds covered with a good humus rich soil. Seeds need repeated cycles of warm and cold before germination.
