Habitat notesNative to South America, Mexico, New Caledonia and Africa. In Hawaii, Sapindus saponaria grows in moist forests on Hualalai, Mauna Loa, and Kilauea. It occurs naturally at elevations ranging from 2,900 to 4,500 feet (Wagner 1990) Found in stream banks, rocky hillsides, woody margins. In shallow soils it remains a small shrub, in deep soils can become a large tree up to more than 25 metres tall.
