General Biology. Growth form. Herb. Life form. Perennial. Reproduction. Seed. Seedbank persistence. Up to 80 years.

Notes. Mat-forming, secondary sand stabiliser that readily spreads by seed into dune areas. Common in the Perth metropolitan area. Germinates in both light and dark conditions. The colour and shape of flowers change due to senescence, pollination and/or nectar withdrawal.

Additional information. Origin. North America. Similar exotic species. Oenothera stricta, O. glazioviana, O. mollissima.

Suggested method of management and control. Control in seedling stage, as older plants resistant to herbicide. Relatively resistant to glyphosate. Hand remove small populations in areas not susceptible to erosion. Spot spray chlorsulfuron 0.4 g/10 L + spray oil. 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.
