Management Notes (for the Swan NRM Region)

Alternative Names. Homeria flaccida.

General Biology. Growth form. Geophyte. Life form. Annually renewed corm. Reproduction. Primarily seed, occasionally corm offsets. Dispersal. Water, soil, cattle droppings. Time to first flowering. 2-3 years. Seedbank persistence. Less than 2 years. Fire response. Generally survives fire. Fire can bring corms out of dormancy and stimulate flowering.

Notes. Up to 60% of corms beneath the soil surface can remain dormant over the winter growing season. Following fire is a particularly important time to control One Leaf Cape Tulip as fire can bring corms out of dormancy and stimulate flowering. All parts of the plant are toxic to stock.

Additional information. Origin. Southern Africa. History of use/introduction. Garden escape. Similar exotic species. Moraea miniata.

Suggested method of management and control. Spot spray metsulfuron methyl 0.2 g/15 L or chlorsulfuron 0.2 g/15 L + Pulse® or 2.5-5 g/ha + Pulse® or 2,2 DPA 55 g/10 L + Pulse®. Apply just on flowering at corm exhaustion. 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.
