This plant can probably only be grown in our zones 9-11, if even in zone 9. The reason is that it requires a great deal of light. Before the pods are completely ripened, they can be eaten fresh or cooked like snap beans. Every part of the plant can be eaten, though, including the roots, which are eaten like potatoes.
