Wine cup tubers can be found in dry, sandy fields, especially in the Texas Hill Country. The leaves are best cooked where their okra-like tendencies can be used to thicken stews. The tubers taste like sweet potatoes and can be eaten raw or cooked. The tubers are biggest in the winter, but are very hard to find then without the wine cup flower showing their location.
The long, almost vine-like stems of wine cups grow in a rosette centered on the tuber. These tubers are covered in fine, delicate roots that often get damaged while digging up the tuber, rendering them unable to survive transplanting. If you dig it you have to eat it, otherwise you're wasting it.
