Ipomoea aquatica

Kangkong, swamp cabbage

A variable water and marsh plant with creeping hollow water-filled stems and shiny green leaves. The big funnel-shaped flowers, 2-5 cm long, are purple or white. Sometimes cultivated for food, and used for pig and cattle feed in Southeast Asia, where it is grown in ponds fertilized with sewage. Very palatable and high yielding. Heavy feeding may cause watery faeces.
