Blue cohosh (Caulophyllum thalictroides)

Blue cohosh (Caulophyllum thalictroides) is a perennial plant that flourishes in shady, forested areas with moist, well-drained soil. It produces clusters of greenish-yellow flowers that eventually develop into blue berries, which are toxic and should not be consumed. The plant's foliage starts as a delicate green in the spring and transitions to a golden-green hue as the season progresses.
