It found in swamps and on the margins of lakes and streams along coastal areas in the Mid West, Wheatbelt, Peel, South West, Great Southern and Goldfields-Esperance regions where it grows in damp silty-sandy soils. It is also found in Queensland, Victoria, New South Wales, South Australia, Tasmania and the Northern Territory.
The upright foliage and spreading rhizomatous habit allow the plant to form large dense swards in wet areas. It can grow in nutrient poor soils in water up to a depth of around 50 centimetres (1.6 ft). The plant tends to grow taller in permanently damp areas and shorter in ephemeral environments. It is suitable for use in artificial wetlands.
