plant sale text: This native legume resembles sensitive partridge pea (Chamaecrista nictitans) but is taller and shrubbier with larger flowers and seed pods. Like other members of the pea family, this species is great for pollinators and other insects. The interesting 4-inch long drooping seed pods turn black and persist on the plant throughout the fall and are relished by doves, quail, and other birds. Deer and other mammals typically leave this species alone due to the leaves being mildly toxic, however there are several species of butterflies that use this species as their larval host plant.
