American Hogpeanut - Amphicarpaea bracteata

Family: Fabaceae - Pea family Genus Common Name: Hogpeanut Native Status: Native
Amphicarpaea bracteata - American Hogpeanut. This thin-stemmed twisting vine is the only species in the Amphicarpaea genus, a member of the Pea family. It twists around other plants and on fences, reaching up to 6 feet in length.

This plant produces flowers along the stem/vine, shown on these pages, and also at the base of the stem. These basal flowers produce an edible bean-like fruit, which apparently can be quite tasty when cooked. Sometimes these fruits develop underground, similarly to a peanut.
