Blue Cohosh

Caulophyllum thalictroides

Overview

Blue Cohosh is an attractive deciduous plant native to North America. Growing 0.5-1m tall, it has smooth, muted blue stems with delicate foliage. In spring, dark blue berries are formed which provide excellent winter foraging for wildlife. It grows best in moist, well-drained soil in partial shade. When given enough moisture and TLC, it produces white, star-shaped flowers each spring. Blue Cohosh is an eye-catching addition to any woodland or naturalized garden and an effective ground cover.
