As a rapidly growing species, it can reach heights of up to 30 m (100 ft) and can live more than 100 years. Its dense foliage provides shade and is grown just for its ornamental value. At the base of the tree, the bark is rough and dark grey, becoming lighter grey and smoother higher up. The wood is water resistant after being kiln-dried. Because of this, it is used in railway sleepers and to install motors in wells. It is sometimes used to make cheap furniture and village dwellings, though it is relatively hard for carpentry.
The leaves which have an aroma similar to turpentine, are pinkish when young, changing to a leathery, glossy dark green with a yellow midrib as they mature. The leaves are used as food for livestock, as they have good nutritional value.
Syzygium cumini trees start flowering from March to April. The flowers are fragrant and small, about 5 mm (0.2 in) in diameter. The fruits develop by May or June and resemble large berries; the fruit of Syzygium species is described as “drupaceous“. The fruit is oblong, ovoid. Unripe fruit looks green. As it matures, its color changes to pink, then to shining crimson red and finally to black color. A variant of the tree produces white coloured fruit. The fruit has a combination of sweet, mildly sour and astringent flavour and tends to colour the tongue purple.
