Management Notes (for the Swan NRM Region)

Alternative Names. Silver Arctotis.

General Biology. Growth form. Herb. Life form. Perennial. Reproduction. Root fragments, very rarely by seed. Dispersal. Soil, plantings, garden refuse.

Notes. Also naturalised in California and southern Australia. Often planted in gardens or as a coastal stabilising plant. Capable of forming large, dense monocultures that smother and displace native species through shading and competition for resources. Highly adaptable, able to thrive in the harsh coastal conditions with hot dry summers, mobile sands, strong winds, salt spray and low winter rainfall. Typical for Arctotis species, flowers only open with sunlight. Pollinated by bees. Seeds ripen quickly within weeks after flowering, however germination of seed is rare.

Additional information. Origin. South Africa. History of use/introduction. Ornamental, coastal erosion control.

Suggested method of management and control. Try manually removing small/isolated populations. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
