Open areas, dry banks, rocky areas.
Sets seed. Vegetative spread from trailing stems. Human-mediated dispersal through dumping of garden waste.
Forms dense mats, displacing native vegetation.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
