Apios americana (Groundnut)
Bruso, George H.

Apios americana Medik.

Groundnut, Wild potato, Indian potato

Fabaceae (Pea Family)

USDA Symbol: apam

USDA Native Status: Native to U.S.

Climbing vine with maroon or reddish-brown pea-like flowers in compact racemes arising from leaf axils.

This legume has a cord-like rootstalk with edible tubers the Indians gathered for food. The Pilgrims relied on them as a food source during their initial years in Massachusetts. The tubers can be used in soups and stews or fried like potatoes; the cooked seeds can also be eaten. The flowers are sufficiently beautiful to warrant cultivation, but the plant tends to take over. The generic name, from Greek for pear, alludes to the shape of the tubers. Prices Groundnut (A. priceana), a rare species with greenish-white flowers and purple tips, occurs in Kentucky, Tennessee, and southern Illinois.
