Late to emerge in spring, this plant grows rapidly and eventually reaches shrub-like proportions. A tall, imposing plant, use as a bold accent or spot it throughout a meadow garden. Wild Senna is a member of the pea family though you wouldn’t know it based on the interesting yellow flowers which are 5-petaled and regular, not pea-shaped. The seed pods that follow give it away, looking much like other members of the family such as black and honey locust – they remain ornamental through early winter. The foliage is purgative for mammals and deer generally avoid it.
