Senna marilandica, commonly called wild senna, is an erect, shrubby, Missouri native herbaceous perennial which typically occurs in open woods and wet meadows and grows 4-6′ tall. Features axillary racemes of brownish-yellow, pea-like flowers clustered atop unbranched stems in summer. Flowers give way to pendant, pea-like seed pods (to 4″ long) which turn black in fall and persist on the plants well after the plant has in the normal course died back to the ground. Feathery, compound, locust-like, dull green leaves (4-8 pairs of oval leaflets). Formerly known as and often still sold as Cassia marilandica.
