Water Chestnuts Facts

Chinese water chestnut is a tuberous, rush-like, marginal aquatic perennial that is probably grown more often for its edible, dark brown tubers (corms) than it is grown for ornamental purposes. Plants produce horizontal rhizomes that terminate in rounded tubers. The tubers are commonly used in Asian cooking. They may be eaten raw or cooked, and are noted for their sweetness and distinctive nut-like crunch. These plants are commercially cultivated in China and Japan for the tubers.
