The leaves are trifoliate, with narrow to elliptic leaflets that are one to two inches long. Leaflets are softly hairy and show distinct venation; the leaf stalks are very short. Stems are also hairy. The plant favors dry to mesic soils in full sun and is common in sandy prairies, old fields, and open savanna ground.
As a legume, it contributes nitrogen to the soil and supports plant diversity. Its deep taproot improves infiltration and anchors the plant during drought, making it valuable in restoration. Wildlife use is well documented: deer and rabbits browse the foliage; upland game birds feed on the seeds; and quail, turkeys, and doves readily consume the nutlets. The eastern‑tailed blue and other small butterflies use bush clovers as larval hosts. Across the year, its structure, forage, and seed production make it an important component of prairie wildlife habitat.
