Résumé

Koster’s curse is a quick-growing invasive plant that has the ability to form dense thickets, smothering native vegetation and causing major problems to primary industries. It will invade disturbed areas including the edges of clearings and stream-banks, along fence lines, paths and roadways. Koster’s curse prefers humid tropical lowlands and waterways and is spread by fruit-eating birds and mammals. A mature bush can produce thousands of purple berries and can produce seeds all year round; it will also reproduce vegetatively (from cuttings, detached leaves and stems). It is a serious pest in at least 16 countries, including Hawaii, Fiji and Indonesia

Danger

Koster's curse is a highly invasive shrub, growing up to 5 m tall. This shrub has the potential to spread rapidly over many parts of Australia. It forms dense thickets that can smother pasture and native vegetation in a similar manner to lantana. The berries produced are easily spread by birds.
