Syzygium jambos has several common names, reflecting the large number of regions in which it occurs as a garden or fruit tree or as an invader. is a large shrub or small-to-medium-sized tree, typically three to 15 metres high, with a tendency to low branching. Its leaves and twigs are glabrous and the bark, though dark brown, is fairly smooth too, with little relief or texture. The leaves are lanceolate, 2 cm to 4 cm broad, 10 cm to 20 cm long, pointed, base cuneate with hardly any petiole, lively red when growing, but dark, glossy green on attaining full size. The flowers are in small terminal clusters, white or greenish white, the long, numerous stamens giving them a diameter of 5 – 8 cm. In temperate regions the tree is summer-flowering.
