USDA Symbol: ambr2
USDA Native Status:
A twining vine with 2 kinds of flowers. Flowers: Those on upper branches 1/2 (1.5 cm) long, pale purple, pale pink, or lilac, in clusters hanging from leaf axils; those on lower or creeping branches inconspicuous, lacking petals.
The genus name is from the Greek amphi (of both kinds) and carpos (fruit) and refers to the two kinds of fruit. The seeds of the upper fruit are inedible, but those from the underground fruit are edible when boiled. Birds feed on the seeds of both kinds of fruit. Hogs eat the seeds of the fruit below ground, hence the plants common name.
