Wild Senna
Senna hebecarpa
Wild senna is the taller sibling of southern senna. it can reach 6–8 feet in rich, moist conditions, creating a substantial back-of-border presence with bold compound leaves and bright yellow flowers through midsummer. Like southern senna, it's a host plant for cloudless sulphur, orange sulphur, and sleepy orange butterflies, whose caterpillars feed exclusively on senna leaves. The clusters of yellow blooms are worked constantly by bumblebees buzzing to release pollen. It naturalizes in moist to wet areas along stream banks and woodland edges, spreading by seed to fill in over time. The large, persistent seed pods turn dark brown and stay on the stems through winter, adding structural interest when the garden is otherwise bare.
