About Jamun (Jambul) and the Jamun Tree

Latin Name: Syzygium cumini

In India, the Syzygium cumini tree and its fruit are known variously as jamun, jambul, jaam, jambul etc. Worldwide, it is known by some other names like java plum, black plum, Indian blackberry, Portuguese plum, jambolana plum, etc.

The Jamun tree is native to India and its bordering countries like Nepal, Pakistan, Bangladesh Sri Lanka and even Indonesia. In 1911, this tree was introduced in Florida by the USDA.

The tree grows equally well in both the tropical and the subtropical regions. Though organised cultivation is not done much, a lot of trees are grown individually by people having land in their backyards. In the wild, however, it grows all over India.

It is a large and hardy evergreen tree and lives for over a hundred years. It starts flowering in the month of March and continues till May. Thereafter, with the onset of monsoon in June, it starts bearing fruit. The flowers are white and have a sweet fragrance.

The fruits do not ripen at the same time and are picked daily. Jambul fruits resemble grapes and are oblong or ovoid in shape. Only ripe fruits are picked as they do not ripen once they are picked. They have a single seed and a soft dark purple coloured almost black skin and a lighter purple flesh. When eaten, the fruits coat the mouth and the tongue a deep purple colour that stays for a few hours.. The fruit is sweet and tart and leaves a slight astringent action in the mouth.

The Jamun tree is revered by the Buddhists.
