Syzygium cumini (family Myrtaceae) is an evergreen tropical tree native to tropical countries from Pakistan throughout Southeast Asia.It is fast growing, reaches up to 30 meters (100 feet) tall and lives up to 100 years.The tree is known as the Java plum tree, for the dark purple, oblong edible fruits it produces (and by many other common names in the various regions in which it grows, including jambul and black plum). The fruit reaches about 2 cm (0.8 in) long and has white or purple flesh.
Java plum trees form dense shady canopies and the trees are grown for their ornamental value. It does well in a range of soil types and environmental conditions. Buddhists and Hindus consider the sacred and worship using the leaves and fruit.Indian emigrants brought it overseas from India and it is common in former tropical British colonies.It has been introduced in Cook Islands, Fiji, French Polynesia, Guam, Hawai‘i, Florida, New Caledonia, Niue, Palau, Tonga, China, Indonesia, Malaysia, Christmas Island, Australia, Africa, India, Caribbean, and South America. However, the canopy shades out young native trees and prevents re-establishment of native forests.It was introduced to Florida in the 1920s, and is now on the Category I listing of the Florida Exotic Pest Plant Council's (FLEPPC) 2013 List of Invasive Plant Species.It also is highly invasive in the Cook Islands, French Polynesia, and Hawaii.
Syzygium cumini is used for many purposes.It is planted for shade and as a windbreak.The wood is water resistant and very hard, so used for building railway cars, beams, bridges, posts, sometimes furniture.The tannin rich bark is used for dyes and leather tanning. Fruits are made into drinks, vinegars, and wines and the leaves are used as food for livestock and silkworms, as they have good nutritional value. The leaves, stems, flowerbuds, opened blossoms, root and tree bark are used for a wide array of alternative/folk medicinal purposes, including skin and digestive system ailments, controlling blood pressure and blood glucose levels, and show antibiotic activity.

Syzygium cumini, commonly known as Malabar plum,[3] Java plum,[3] black plum, jamun, jaman, jambul, or jambolan,[4][5] is an evergreen tropical tree in the flowering plant family Myrtaceae, and favored for its fruit, timber, and ornamental value.[5] It is native to the Indian subcontinent and Southeast Asia, including Myanmar, Sri Lanka, Bangladesh and the Andaman Islands.[4][2] It can reach heights of up to 30 metres (98 ft) and can live more than 100 years.[4] A rapidly growing plant, it is considered an invasive species in many world regions.[5]
The name of the fruit, black plum, is sometimes mistranslated as blackberry, which is a different fruit in an unrelated order. Syzygium cumini has been introduced to areas including islands of the Pacific and Indian Oceans, Australia, Hong Kong and Singapore.[6]
The tree was introduced to Florida in 1911 by the United States Department of Agriculture, and is commonly grown in tropical and subtropical regions worldwide.[5] Its fruits are eaten by various native birds and small mammals, such as jackals, civets, and fruit bats.[5]
As a rapidly growing species, it can reach heights of up to 30 m (100 ft) and can live more than 100 years.[4] 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.[4] 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.[4]
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.[7]
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".[8] 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.[4]
This species is considered invasive in Florida, South Africa, parts of the Caribbean, several islands of Oceania, and Hawaii.[5][6]
Jambolan fruits have a sweet or slightly acidic flavor, are eaten raw, and may be made into sauces or jam.[4] Fruits may be made into juice, jelly, sorbet, syrup (e.g., kala khatta),[9] or fruit salad.[4]
Raw fruit is 83% water, 16% carbohydrates, 1% protein, and contains negligible fat. In a 100 gram reference amount, the raw fruit provides 60 calories, a moderate content of vitamin C, and no other micronutrients in appreciable amounts (table).
The 1889 book 'The Useful Native Plants of Australia’ records that the plant was referred to as "durobbi" by Indigenous Australians, and that "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. It is eaten by birds, and is a favourite food of the flying fox (Brandis)."[10] The fruit has been used in traditional medicine.[4][5]
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 Pāli word jambu is understood by Pāli dictionaries to refer to the Syzygium cumini which they often translate as the Rose-apple tree.[11]
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.[12]
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 neredu tree (as it is called in the region's language, Telugu) is used in Andhra Pradesh to make bullock cart wheels and other agricultural equipment. The timber of neredu 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 naval pazham in Tamil. 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 naval pazham 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.[13]
