American Senna (Senna hebecarpa)
American Senna is a large 3' to 8' tall native long-lived native perennial legume. This is a summer flowering plant easily recognized by the large terminal racemes of bright yellow pea-like flowers growing in the axis of the compound leaves. This Senna will grow well in dry to moist soils and full sun to partial shade, however, the native range is restricted to the northern states. The striking appearance and easy establishment make this a great garden plant. American Senna is a valuable wildlife plant, providing cover and food for wildlife, especially quail.
