Native to South Africa, gazania (Gazania spp.) was introduced to Australia as an ornamental garden plant, valued for its vibrant flowers and ability to thrive in dry conditions. However, some species have escaped cultivation and established in coastal dunes, roadsides, agricultural land and inland grasslands.
Gazania is an environmental and agricultural weed of concern across southern Australia and parts of Western Australia. Its tolerance of drought and high temperatures allows it to persist in harsh conditions, while its ability to produce large quantities of seed helps it spread into new areas.
Once established, gazania can form dense groundcover, competing with native plants for sunlight, water, nutrients and space. This can reduce native plant diversity and affect wildlife by limiting the availability of natural food sources and habitat. Infestations in agricultural areas can also create challenges for landholders.
Gardeners and landholders can help prevent further spread by identifying and removing gazania before it sets seed, disposing of garden waste responsibly and choosing suitable native groundcovers instead.
By preventing the spread of invasive weeds like gazania, we can help protect our local landscapes, support native wildlife and maintain healthy ecosystems.
