• is botanically known as Syzygium cumini and is
produced on an evergreen tree that reaches up to 20
feet tall. In its native India, the fruit is also called
Jambul or Jaam. Around the world the small fruit is
known as Java plum, Black plum and Indian blackberry.
The Jamun tree is revered by Buddhists; in Indian
mythology, Lord Rama subsisted on Jamun fruit during
his 14-day exile in the forest. This lore earned the fruit
the nickname “fruit of the Gods.” The Jamun tree lives

5. Varieties
• The common types of jambolan in India are: 1) Ra
Jaman, with large, oblong fruits, dark-purple or bluish,
with pink, sweet pulp and small seeds; 2) Kaatha, with
small, acid fruits. Among named cultivars are,
mainly, 'Early Wild', 'Late Wild', 'Pharenda'; and,
secondarily, 'Small Jaman' and 'Dabka' ('Dubaka'). In
Java, the small form is called Djoowet kreekil; a
seedless form is Djoowet booten. In southern Malaya,
the trees are small-leaved with small flower clusters.
Farther north, the variety called 'Krian Duat' has larger,
thicker leaves and red inner bark. Fruits with purple
flesh are more astringent than the white-fleshed types.
