What you need to know
Although gazania is not a legally declared pest plant, it may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.
Coastal areas, dunes, grassland, rocky outcrops, cliffs, riparian margins, wasteland, roadsides.
Seeds dispersed by wind, water and attachment to animals. Vegetative spread from stem fragments. Human-mediated dispersal through dumping of garden waste, deliberate plantings and movement of contaminated vehicles and clothing.
Impact on environment
Competes with and suppresses native coastal 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.
Method: Dig out.
Plant parts requiring disposal: All parts.
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol is currently not available for this species.
