Amphicarpaea bracteata (hog-peanut or ground bean) is an annual to perennial vine in the legume family, native to woodland, thickets, and moist slopes in eastern North America.[2]

Description[edit]

Leaves have three leaflets and are held alternately on twining stems.

Flowers are pink to white and bloom from late summer to autumn. The flowers are either open for cross-pollination or closed and self-pollinating. The closed flowers may be above or below ground.[3]

Seeds from open flowers are held in a flat pod, pointed at both ends, that dries when mature and twists to release the seeds. Seeds from closed flowers are held in round pods with a single seed each. The roots and seeds are edible.[4] The seeds which become subterranean from flowers on stolons give it the name peanut.[5]
