Ipomoea aquatica is a semiaquatic, tropical plant grown as a vegetable for its tender shoots and leaves. It is found throughout the tropical and subtropical regions of the world, although it is not known where it originated. This plant is known in English as water spinach, river spinach, water morning glory, water convolvulus, or by the more ambiguous names Chinese spinach, Chinese Watercress, Chinese convolvulus, swamp cabbage or kangkong in Southeast Asia. Occasionally, it has also been mistakenly called "kale" in English, although kale is a strain of mustard belonging to the species Brassica oleracea and is completely unrelated to water spinach, which is a species of morning glory. It is known as phak bung in Thai and Laotian, ong choy in Cantonese, kongxincai (空心菜) in Mandarin Chinese, rau muống in Vietnamese, kangkong in Tagalog, ကန်စွန်း, gazun in Myanmar, trokuon (ត្រកួន) in Khmer, kolmou xak in Assamese, kalmi saag in Hindi, kalmi shak in Bengali, Thooti Koora in Telugu, kangkung in Indonesian, Malay and Sinhalese and hayoyo in Ghana. In Suriname (South-America) it's known as dagoeblad or dagublad.
