About
Syzygium jambos is a species of rose apple originating in Southeast Asia and occurring widely elsewhere, having been introduced as an ornamental and fruit tree.
Where it grows
It has also been introduced widely on every continent except Antarctica, and it has become established and invasive in several regions. Concern has been expressed because of the threat to various ecosystems, including those on several Hawaiian islands, Réunion, Pitcairn, the Galápagos Islands, parts of Australia and the warmer regions of the Americas. However, in Hawaii, it has been almost wiped out by the introduced rust Puccinia psidii.
Uses
Rich in vitamin C, the fruit can be eaten raw or cooked in various regional recipes. In South-East Asian countries, rose apple fruit is frequently served with spiced sugar.
