Wild Senna offers a profusion of buttery yellow flower clusters atop lush green foliage in midsummer. The dark brown seedpods are a favorite of birds, and add great winter interest, too. Fond of clay, it thrives in medium to moist soils, and tolerates periodic flooding. The horizontal root system provides stabilization against high wind velocities, making this tall sun-loving plant an excellent hedge choice. An exceptional plant for pollinator support, Wild Senna attracts a plethora of pollinators to its rich yellow blooms. Several small butterflies use Wild Senna as a larval host plant, including the Cloudless Sulphur (Phoebis sennae), Orange barred sulpher (Phoebis philea), and the Silver Spotter Skipper (Epargyreus clarus).
