A hardy, clumping native grass with narrow, dark green leaves that forms attractive upright bunches. Excellent for erosion control and landscaping in dry conditions with minimal water and maintenance needs.

Why grow it

Mat rush establishes quickly in poor soils and tolerates more sustained drought than many ornamental grasses, making it practical for erosion control on slopes and in water-limited regions. Compared to exotic ornamental grasses, it requires less fertilizer and performs reliably in Australian native plantings without the management demands of more temperamental species.

Watch out for

Plants can take 2-3 seasons to reach full density, so erosion control effectiveness may be modest in the first year after planting. In poorly drained or consistently wet soils, root rot can develop, so site selection is important even though the species tolerates a wider range of conditions than many natives.
