Syzygium cumini, also known as Malabar plum,[ black plum, jamun, jaman, jambul, jambolan or Indian blackberry, is an evergreen tropical tree in the flowering plant family Myrtaceae, and favored for its fruit, timber, and ornamental value.][ It can reach heights of up to and can live more than 100 years.]
Syzygium cumini has been introduced to areas including islands of the Pacific and Indian Oceans, Australia, Hong Kong and Singapore.
The tree was introduced to Florida and is grown in tropical and subtropical regions worldwide.[ Its fruits are eaten by various native birds and small mammals, such as , , and megabat.][

Description
Its dense foliage provides shade and is grown 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 aromatic leaves 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.[ The encyclopedia of fruit & nuts, By Jules Janick, Robert E. Paull, p. 552]
Syzygium cumini trees start flowering from March to April. The flowers are fragrant and small, about 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.[

The 1889 book The Useful Native Plants of Australia states that this plant (referred to by the synonym Eugenia jambolana) was called durobbi by some Indigenous Australians."The fruit is much eaten by the natives of India: in appearance it resembles a damson, has a harsh but sweetish flavour, somewhat astringent and acid. Is much eaten by birds; a favourite food of the large bat (Pteropus). A kind of vinegar is prepared from it, which is used in diseases of the spleen."
The fruit has been used in traditional medicine.[

Cultural and religious significance in India
In the Majjhima Nikāya, three parallel texts (MN 36, MN 85 and MN 100) claim that the Buddha remembered an experience of sitting in the cool shade of a jambu tree when he was a child. While his father was working, he entered into a meditative state which he later understood to be the first stage of Jhāna meditation. The texts claim that this was a formative experience, which later encouraged him to explore and practise Jhāna meditation, and that this then led to his Awakening. The Pali word jambu is understood by Pāli dictionaries to refer to the Syzygium cumini which they often translate as the Rose-apple tree.[Rhys-Davids, Pali-English Dictionary; Cone, Dictionary of Pali]
Krishna was said to have four symbols of the jambu fruit on his right foot as mentioned in the Srimad Bhagavatam commentary (verse 10.30.25), "Sri Rupa Chintamani" and "Ananda Candrika" by Srila Visvanatha Chakravarti Thakura.
In Maharashtra, Syzygium cumini leaves are used in marriage pandal decorations. A song from the 1977 film Jait Re Jait mentions the fruit in the song "Jambhul Piklya Zaadakhali".
Besides the fruits, wood from tree (as it is called in the region's language, Telugu language) is used in Andhra Pradesh to make bullock cart wheels and other agricultural equipment. The timber of is used to construct doors and windows.
Legend in Tamil Nadu speaks of Avvaiyar (also Auvaiyar or Auvayar) of the Sangam period and the jamun fruit, called in Tamil language. Avvaiyar, believing to have achieved everything that is to be achieved, is said to have been pondering over her retirement from Tamil literary work while resting under tree. There she was met with and was wittily jousted by a disguised Murugan, regarded as one of the guardian deities of Tamil language, who later revealed himself and made her realize that there is still a lot more to be done and learnt.
