This vine is a common plant that grows in fields and along trails. The swollen underground tuber was boiled or roasted and eaten like a potato. Colonial people have even called it Indian potato.
Groundnuts can be eaten raw but are usually boiled or roasted and then added to soups and stews. They have a mild flavor and are used much like potatoes, but they are more nutritious. In fact, groundnuts contain three times the protein of a potato. These tubers can also be stored, similar to potatoes, in a cool, dry area for an extended period of time
