Native to the Midwest, Senna hebecarpa is an upright-growing member of the pea family, which produces golden-yellow spikes of flowers in the summer and early fall. Tough, woody, unbranched stems rise from the ground and produce compound leaves with small toothless ovate leaflets. The flowers give way to dark brown seedpods that last into winter. Branches often bend under the weight of the seedpods. The seeds are relished by grouse and turkeys. Bees love the flowers, and caterpillars like the foliage, although it is slightly toxic to humans and deer. It reaches a height of approximately 5 feet under full sun and, preferably, moist soil conditions. The plant is ideal as a specimen in a border.
