Ipomoea aquatica, known as water spinach, water morning glory, water convolvulus, ong-choy, kang-kung, or swamp cabbage, is popularly used as a green vegetable, especially in East and Southeast Asian cuisines. In the USA ipomoea aquatica is a Federal Noxious Weed, and can be illegal to grow, import, possess, or sell without permit. However, a market exists for the plant's powerful culinary potential. See: USDA weed factsheet. As of 2005, the state of Texas has acknowledged that water spinach is a highly prized vegetable in many cultures, and has allowed water spinach to be grown for personal consumption, in part because it is known to have been grown in Texas for more than 15 years and has not yet escaped cultivation. Because it goes by so many names, it can easily be slipped through import inspections, and it is often available in Asian or specialty produce markets.
