Kangkong, also known as water glorybind, water spinach, water convolvulus, and swamp cabbage, is an important green leafy vegetable in Southeast Asia, Taiwan, and Malaysia. It is found throughout the fresh waters of southern China, and is cultivated in countries such as Ceylon. Kangkong has not become very popular elsewhere, particularly here in Florida where its production is discouraged. Our climate is favorable, and given wet soil conditions it would produce well here. Tight precautions should be taken to see that it does not become an established weed in our waterways. The Florida Department of Natural Resources must issue a special permit to anyone wanting to grow kangkong.
