A plant of the dry to moist tropics, where it is found at elevations up to 1,200 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 32°c, but can tolerate 10 - 36°c[1]. It prefers a mean annual rainfall in the range 700 - 1,500mm, but tolerates 500 - 1,700mm[1]. The plant can tolerate up to 2,500mm annual rainfall[2, 3]. Prefers a sunny position[2, 3]. The plant is widely adapted, found growing in both alluvial and clay soils[2]. Succeeds on a variety of soils but is most common where pH is higher than 5.5[3]. Prefers a pH in the range 6 - 7, tolerating .5 - 7.5[1]. The plant can escape from cultivation and become a weed tree in areas outside its native range[1]. A fast-growing tree[4]. The tree can flower all year round in the more equatorial part of its range[3].

Propagation

Seed - requires scarification before planting[2]. Pour boiling water over the seeds, let them soak for 30 seconds and then drain[2]. With fresh seed, germination occurs in 7 - 14 days at a rate of 60 - 80%[2]. Seedlings are ready for out-planting when they reach a height of 30 - 40cm (about 15 weeks)[2]. The plant can also be established by direct seeding[2]. Cuttings[2].
