Description
A semi-deciduous tropical tree that can reach up to 50-60ft, though many specimens remain shorter. Leaves are arranged in leaflets, with up to 10 pairs per leaf. Fruits grow to 1-1 1/2" and ripen to a yellow-orange color. Each fruit contains a single large, hard-shelled seed.
Hardiness
Exact hardiness unknown. Some of its near relatives survive freezes, but this tropical native is probably not hardy to hard freezes or prolonged frosts.
Growing Environment
Grow in full sun. Provide regular water, particularly during warm months. Grow in well-drained soil.
Propagation
By seeds. Seeds should be soaked in lukewarm water for 24hrs prior to planting. Seeds typically germinate in several weeks to a few months.
Uses
Dried fruits are used as soap. In recent years the dried fruits have been marketed for washing clothes. A couple of them added to a load of laundry in the washing machine works much like your favorite detergent.
Native Range
Native to Asia, concentrated in parts of India.
