Caulophyllum thalictroides aka Blue Cohosh

Caulophyllum thalictroides, commonly known as blue cohosh, is a medium-tall perennial herb belonging to the Berberidaceae family. It features bluish-green foliage and produces blue berry-like fruits. The plant derives its common name from an Algonquian word meaning "rough". The Greek-derived genus name Caulophyllum refers to its stem-leaf structure, while the specific name thalictroides highlights its resemblance to the highly divided, multiple-compound leaves of meadow-rues. This rhizomatous perennial bears leaves divided into three leaflets and sprouts small, green or yellow-brown, star-shaped flowers in spring. Following the flowers, it produces deep, bright blue, berry-like seeds that can reach up to 1cm in diameter. Blue cohosh is typically found in moist woods within forested or natural areas.
