Apios americana aka Apios

Apios americana, also known as the American groundnut, potato bean, hopniss, Indian potato, hodoimo, America-hodoimo, cinnamon vine, or groundnut, is a slender, herbaceous perennial climber that produces edible beans and large tubers. This native vine, belonging to the legume family, can be found in tidal and non-tidal marshes, wet thickets, stream banks, and bottomland forests. Its leaves are composed of five or seven pointed leaflets, and it bears scented, pea-like flowers in late summer and early autumn. The flowers exhibit a pale brown exterior and a dark reddish-brown interior. While it is only cultivated as a food crop in Japan, the common groundnut offers numerous health benefits due to its nutritious fruits and tubers.
