Dry deciduous forests. In areas with a marked dry season, it sheds its leaves during the drought, but in
other areas it is virtually evergreen. It requires a tropical or near-tropical climate, but can tolerate
drought and salty conditions. It prefers an open, free-draining sandy or loamy soil enriched with
organic matter. The tree does not like heavy or clay soils and flowers more profusely when kept slightly
Native to Madagascar (where it has become rare due to forest overexploitation), but currently cultivated
pan-tropical as an ornamental.
In addition to its ornamental value, it is also a useful shade tree in tropical conditions, because it
usually grows to a modest height but spreads widely, and its dense foliage provides full shade. The
inner portion of the seed is eaten in Thailand. The bark is believed to be antipyretic, used in subsiding
