Notable Characteristics of Blue Cohosh Plant
Blue Cohosh can be identified mainly by its stalks and leaves. A thin, single stalk grows erect from the ground, with equally thin branches growing off of it and branching into three leaves. The leaves are varying in size, with round edges that come to a point at the end.
They are thin and silky, and their blue-green color is particularly eye-catching in large patches. The six petals of the flower are a dark purple-brown with yellow stamens that bloom in the spring, but dry out and curl into themselves before falling off in the summer. Bright blue berries grow in their place which add a beautiful, bold pop of color to the lush green leaves.
This plant is an important North American native because it is fully edible. The seeds can be a substitute for coffee, the root is commonly used to treat pain from menstruation, or even return the reproductive cycle back to a normal pattern. You can make the berries into a tincture to treat arthritis or other body aches, and combine it with ginger, turmeric or solomon's seal to help your digestion.
