A very hardy, fast-growing coastal native tree that is found naturally throughout Asia (Pantropic). The Pongamia is long-lived and thrives in wet and dry tropical areas and will even grow with its roots in saline water of river estuaries. In India it has been cultivated for over 3000 years as a useful source of lamp oil (biofuel) and a natural medicine. It produces terminal clusters of pink flowers that stand well clear of the broad, glossy green leaves. Useful as a shade tree, it may reach a height of about 15 m, with a similar spread and is suitable for small to medium-sized gardens.
