Description
- Large fast-growing much-branched sprawling shrub from Central and South America, with square brittle prickly stems. Can become vine-like, and scramble up into trees and shrubs.
- Lantana is spread into bushland by fruit-eating birds, and also by the dumping of garden waste. Stems lying on moist soil will layer (grow roots).
- Flower heads are flat, 2-3cm across, consist of many tiny tubular flowers, and come in a variety of colours from cream through pink and red, often in combination. Flowers most of the year.
- A cluster of fleshy purplish-black berries follows the flower.

Impact on Bushland
Aggressively invades rich soils in open forest, disturbed rainforest and creeklines, competes vigorously with native species, forms impenetrable thickets, creates dense shade and heavy leaf litter. Reduces biodiversity, transforms ecosystems.
Distribution
Lower Blue Mountains.
Alternative Planting
Native Plants
Dense local native shrubs:
Spike Wattle (Acacia oxycedrus)
Needlebush (Hakea sericea)
Blackthorn (Bursaria spinosa)
Mountain Devil (Lambertia formosa).
