It is native to humid and sub-tropic environments and is common along waterways or seashores, with its roots in fresh or saltwater. It occurs naturally in lowland forest on limestone and rocky coral outcrops on the coast, along the edges of mangrove forest and along tidal streams and rivers.

(1)It grows along river-banks and close to the sea in tidal estuaries in Bangladesh, tolerating a wide range of climates and soils. Approximate limits north to south: 30°N to 20°S. Altitude range: 0 - 1200 m (2)This species grows to elevations of 1200 m, but in the Himalayan foothills is not found above 600 m (GOI 1983). The natural distribution of pongam is along coasts and river banks in India and Burma. Native to the Asian subcontinent, this species has been introduced to humid tropical lowlands in the Philippines, Malaysia, Australia, the Seychelles, the United States (Little undated), and Indonesia. [this is a LOWLAND species, although some planted specimen may occur above 1000 m] (3)USDA zones 10B through 11

(1)Bees and wasps were found collecting floral rewards from different individuals, contributing to both self- and cross-pollination. The bees mentioned above were found to move between flowers fast, spending a small amount of time in search of more floral rewards.
