This is Jamun (Syzygium cumini): A Nutrient-Rich Fruit with Amazing Health Benefits

Overview of the Jamun Tree

The Jamun tree, also known as Black Plum, Indian Blackberry, or Java Plum, is a large, woody tree with thick bark and slightly flattened branches. Its leaves grow in opposite pairs, resembling oval-shaped eggs, with a glossy dark green upper surface and a lighter underside. Mature leaves turn thin, light brown, and have faint glandular dots. The tree’s petiole typically measures 1–2 cm in length.

Its scientific name is Syzygium cumini (L.) Skeels, belonging to the Myrtaceae (Myrtle) family. Jamun flowers grow in loose panicles at leaf axils, with delicate ivory-white blossoms. The fruit develops into an elongated, slightly curved shape with a sunken apex. The seed inside is round. The flowering season occurs between March and August, leading to fruit ripening and harvest.

When unripe, the fruit has a sour and astringent taste. As it matures, it turns deep purple with a sweeter taste, making it more palatable.
