I’M A WEED
Gazania linearis / rigens
Tough, low-growing clump forming perennial herb with a short branched woody rhizome (spreading underground stem) and variable, lance-shaped or lobed leaves, 5-18 cm long, 0.3-2 cm wide, dark green
above, white-woolly below.
Flowers are brightly coloured, large, bronze, yellow and orange daisy-like to 8 cm in diameter all year round. Naturalised on coastal dunes and along some roadsides.
Threat / Problem
• Forms dense patches in disturbed areas of coastal sands and dunes and displaces native vegetation. It withstands salt-laden winds and grows vigorously in sandy soils.
• Reproduces vegetatively and from seed. It produces abundant wind-blown seeds and is often spread in garden waste and through soil movement.
• Hand pull small plants and dig out larger plants ensuring all root fragments are removed.
• Chemical control can be effective. Resistant to Glyphosate®
herbicide but susceptible to Lontrel®.

OR GROW ME
