Blue Cohosh Caulophyllum thalictroides
Caulophyllum thalictroides (Blue Cohosh) is a beautiful woodland plant with a preference for rich moist conditions, typical of a woodland floor. Compound leaves fill out the single leaf stalk with a lacy effect similar to Meadow Rues. New foliage can show a tint of blue or purple pigment. The flowers are greenish yellow to greenish brown and form clusters. They are followed by berries that ripen to a deep blue which are poisonous.
