Amorpha fruticosa is a(n) perennial shrub, which grows 1 m to 3.5 m in height. This species is commonly found on the eastern and southern edges of the Black Hills along moist stream banks, in the open or in open woods. The leaves are mainly at branch tips, alternating, pinnately compunded, composed of many small leaflets rather then dark green leaflets. Amorpha fruticosa has slender racemes, purple with yellow stamens flowers that bloom from June to August.
Additional Notes: False indigo is not generally browsed. Northern Plains Indians used its straight branches for arrow shafts.
