Arachis pintoi
Perennial or pinto peanut species and cultivars are low growing, about 8 inches (20 cm) high, non-twining, nitrogen-fixing legumes. The plants have four oval leaflets on each petiole and light to dark yellow, pea-like flowers. Varieties can differ slightly in leaf size, shape and color. The seed is an underground nut, one per pod, which is not edible.
The Perennial Peanut makes an excellent ground cover in areas with well-drained soil and full sun.
