Native to the Azores, Madeira and Canary Islands, candleberry myrtle is an evergreen shrub or small tree that displaces native trees. It is a serious weed of Hawaii.
Candleberry poses a serious threat to native plants in lowland forests and shrublands, where it forms dense, single-species stands. On the island of Hawaii, it forms a dense canopy with an understory devoid of other plant life. The roots of candleberry myrtle manufacture nitrogen, which allows it to invade recent, nutrient-poor sites much sooner than native plants. Invasion by candleberry myrtle prevents typical plant community succession from occurring.
Candleberry myrtle is a prohibited invasive plant under the Biosecurity Act 2014.

- Not recorded in Australia.
- Small fruits produced in June (northern hemisphere summer).
- Out-competes native plant species and capable of forming dense, single-species stands.
- Modifies forest habitat by significantly increasing nitrogen levels in the soil, which makes the area inhabitable to native plants, but more suitable for other invasive species.
- Able to colonise as wide range of habitats due to its ability to alter soil chemistry.
How it is spread
