Caulophyllum thalictroides
Blue Cohosh
Description
Caulophyllum thalictroides, or Blue Cohosh, is a 2-3 foot perennial for moist rich woods. Its beautiful foliage appears in spring turning from purple-green to blue-green. Star-shaped yellow flowers on Blue Cohosh appear in early spring and its deep blue-black berries form in summer. The seeds are primarily dispersed by birds. The plant was used historically for heavy periods, rheumatism, and gastrointestinal issues. However, many parts of the plant are toxic if eaten in large amounts.
Caulophyllum thalictroides is also known as Papoose Root or Squaw-root.
