rose apple originating in Southeast Asia and occurring widely elsewhere, having been introduced as an
ornamental and
fruit tree

; in fact, the fruit is so like the guava in appearance that people unfamiliar with it may mistake it for a guava on sight. However, the fragrance, flavour and texture are different, and instead of containing dozens of small, hard seeds set in a jelly-like tissue, as a guava does, the fruit of ''S. jambos'' usually contains one or two large, unarmoured seeds about a cm in diameter, lying loose in a slightly fluffy cavity when ripe. Shaking a fruit to feel whether the seeds rattle, gives some indication whether it is ripe. The skin is thin and waxy. The flowers are described by some as fragrant, though this appears to be a variable attribute. The ripe fruit, however, has a strong, pleasant floral bouquet, hence such common names as "Rose apple" and "pomarrosa".

The tree has variously been allocated to the genus ''Jambosa'', ''Eugenia''
[Chittenden, Fred J. Ed., Royal Horticultural Society Dictionary of Gardening, Oxford 1951] and ''Syzygium'', where it now seems to have been permanently accepted. There have been a few species ascribed to it, but currently several varieties with various fruit colours all are recognised as ''Syzygium jambos''.
Common names
''Syzygium jambos'' has several common names, reflecting the large number of regions in which it occurs as a garden or fruit tree or as an invader. The names include ''ಪನ್ನೇರಳೆ '', ''Guljamun '', ''madhura nelli'', Malabar Plum, ''Panineer Champakka'', ''Mountain Apple (champoo),'' ''chom pu'' or ''chom-phu''.

Varieties
There are many varieties of ''S. jambos'' worldwide, including nondescript feral trees. In Thailand the commonest cultivated variety bears a pale green fruit. Malaysian varieties generally have red skins. In many regions the fruit is a shade of pale yellow, often with a slight blush. The skin is thin and waxy, and the hollow core contains a small amount of insignificant fluff. The flesh is crisp and watery, and the taste is characteristic, which leads to some fanciful descriptions such as: "like a cross between
