I’M A WEED
Perennial, often with a robust creeping rhizome to 1.2 m high. Leaf blades are flat or rolled, to 0.4 cm broad. Seed head is narrow 4-20 cm long, often one-sided, slightly hairy, straw-coloured.
Found in sandy areas, including coastal rear dunes, mallee and woodland in higher rainfall parts.
Threat / Problem
• Invades disturbed areas, displacing native species.
• Reproduces vegetatively and from seed, spread mainly through wind, water and movement of contaminated soil.
• Manually remove individual plants, ensuring all rhizomes are removed, bag and dispose of by deep burial if seed is present.
• Spot spray larger infestations, in Autumn before flowering.
GROW ME INSTEAD
Attractive tufted perennial grass that can grow to 1.5 m. Leaves are 10-50 cm long and 0.2-0.5 cm wide, green to grey drying to an orange brown in summer. Flowering from December to February, it produces large distinctive red-brown spikelets with black awns 4-7 cm long.
It commonly grows in grassland and open woodland in full sun to part shade on sandy to clay soils and needs little water once established. Massed planting make an attractive garden feature.
OR GROW ME
Erect, tufted perennial grass with blades flat or in-rolled, to 0.2 cm wide and 12 cm long. Flowering head is a more or less compact panicle (elongated, branched clusters of flowers) that has a bristly appearance, forming on the end of erect stems that protrude above the leaves. Seeds have a fluffy appearance with rows of hairs and a single bent awn (bristle). Found in the understorey of mallee and grassy woodlands.
