Caulophyllum is a hardy perennial that reaches heights of 50 to 90 cm (20 to 36 inches).
They have compound juvenile leaves of blue-green, and green adult leaves. Plants bloom in May, and this is followed by pretty fruits of blue.
Caulophyllum plants have the common names of Blue Cohosh, Papoose root, and Squaw root. Latin names include Caulophyllum thalictroides.

Blue Cohosh and other Caulophyllum plants should be grown outdoors. Plant the roots at a depth of 2.5cm (1 inch) into a location with a moist, wood soil of pH 4.5 to 7.
They should be spaced at about 30 to 40 cm (12 to 16 inches) apart. It is imprtant that they grow in shady areas.
Further plants can be created by dividing the plants in early autumn. Alternatively take cuttings from the roots (complete with rhizomes). Do not eat these plants as blue cohosh can induce labor!
