Syzygium cumini, commonly known as the Java plum, Indian blackberry, or Jamun, is a tropical tree native to the Indian Subcontinent, Southeast Asia, and surrounding regions. It belongs to the flowering plant family Myrtaceae. The tree is known for its small, sweet, and sour fruit, which is often used in various culinary preparations and traditional medicine.
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.
