Menispermum canadense Canadian moonseed


Canadian moonseed is a decidious, twining (no tendrils) woody vine growing up to 20 feet tall. Small dioecious clusters of greenish-white flowers are borne in the leaf axils. Flowers are 3-merous with all flower parts distinct. Each female flower in a cluster ripens into a berry-like drupe.
