About this weed
This native of southern Africa was probably introduced as a garden plant.
Moraea is a cormous, perennial, growing to 0.5 m high. It has yellow flowers in late spring and early summer. The flowers open late in the afternoon and they give off an unpleasant smell. Reproduction is by seed but occasionally offsets. The corms are annually renewed. Seed is dispersed by soil, water and birds. The time to first flowering is 3 years. It generally survives fire.
Impact on Bushland
Found in a small number of locations on roadsides, in Wandoo woodlands and in clay wetlands from Moora to Bunbury and inland to Greenhills. It prefers brown clay or sandy clay and grey loam. Also, it can be found in wet areas, and on track edges and roadsides.
Priority for removal
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. Optimal spraying months are September and October.
