Notes
Yellow ixia (Ixia maculata) is regarded as an environmental weed in Victoria and Western Australia. It has escaped cultivation and become naturalised in open woodlands, around old settlements, along roadsides, and in disturbed sites and waste areas. Like other corm and bulb producing species, yellow ixia (Ixia maculata) spreads from disturbed areas into nearby natural areas, crowding out the plants which native animals depend for food.
In south-western Western Australia, yellow ixia (Ixia maculata) has invaded woodlands from Perth to Albany and inland to the Darling Ranges. In Victoria, it is listed as an environmental weed in Moyne Shire and in the Goulburn Broken Catchment. It has also been recorded in conservation areas in Victoria (i.e. Yarra Bend Reserve and Kaweka Wildflower Reserve), Tasmania (i.e. Gresswell Reserve and Greens Beach/Kelso Coastal Reserve) and Western Australia (i.e. the Brixton Street and Associated Wetlands).
