About this weed

This Oxalis species is easily distinguished as it grows to only about 0.2 m high and has bright pink to purple to white flowers, all have yellow throats, flowering from autumn to spring. It is not known to set seed in Australia and like the other Oxalis it is a native of South Africa.

Description

The weed is a very low growing weed and has distinctive circular leaves forming a rosette. The leaves are often purple underneath. There are three naturalised colour forms: rose-purple, mauve or white. The bulb is annually renewed and many bulbils are produced. It generally survives fire.

Impact on Bushland

If left will spread over bushland and impact on native plant communities.

Location

Widespread in heavier soils in the Perth Metropolitan Area and the South-West Region. It can be found in lawns, crops, pastures and on roadsides.

Priority for removal

High: major threat to the conservation values of bushland if it becomes established.

Management (hand)

Exercise care if manually removing as physical removal can result in spread of bulbils.

Management (herbicide)

Spot spray metsulfuron methyl 0.2 g/15 L + Pulse®, or 1% Glyphosate. Apply at bulb exhaustion, generally just on flowering. Read the manufacturers’ labels and material safety data sheets before using herbicides. May and June are best months to spray weed.
