Rose myrtle
Rhodomyrtus tomentosa · Myrtaceae · also known as Hill gooseberry, Kemunting, Downy rose myrtle, Isenberg bush
A sweet purple berry of a downy-leaved Asian shrub — soft, aromatic, and honey-sweet with a hint of nut, gathered from hillsides across South China and Southeast Asia. A beloved wild snack and wine fruit, and a notorious invader where it has escaped.

Eating rose myrtle: what to know
What regular consumption looks like
Rose myrtle is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of fibre (about 3 g per 100 g), which supports digestion and satiety. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Rose myrtle contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The rose myrtle is a fruit woven into childhoods across southern China and Southeast Asia. On sunny hillsides, its downy-leaved shrubs hang with soft purple berries — sweet, mild, and honeyed with a faint nutty aroma — that generations have gathered by the handful as a wild summer treat.
A sweet hillside berry with a dark side
Known as gangnian in South China and kemunting in the Malay world, the ripe berries are eaten fresh, dried like raisins, and — most famously — made into jam, cordials, and a prized country wine, especially in South China and Vietnam. Its fruit, leaves, and roots also feature in Chinese and Southeast Asian traditional medicine for the stomach and blood. But the same qualities that make it a generous wild food — hardiness, prolific fruiting, easy seeding — have made it a menace abroad: rose myrtle is one of the worst invasive weeds in Florida and Hawaii, where it smothers native habitat. A beloved berry at home and an ecological problem away, it’s the same sweet purple fruit either way — best enjoyed on a Chinese or Malay hillside, warm off the bush. A Myrtaceae cousin of the guava and jamun (duhat), it’s one of Asia’s most cherished wild snacking berries.
