The waterberry or umdoni (isiZulu), as Syzygium cordatum is commonly known, is a common tree of the South African east coast. It also grows in the northern inland parts of the country and in several African countries to the north. The habitat is riverine forest and other water rich areas.
The fruits are eaten by children, animals and birds. An alcoholic drink is prepared from the fermented fruits. The wood is used in carpentry and boat building after water seasoning. Several medicinal uses are known for parts of this tree in local traditional healing. The tree is often planted in gardens, parks and at roadsides (Coates Palgrave, 2002; www.plantzafrica.com).
