Gahnia aspera known as the rough saw-sedge or round sawsedge is a tussock forming perennial plant, often seen in moist situations. The long strap like leaves grow to 80 cm long.[1]
Gahnia aspera grows as a strappy tussock 50–100 cm (20–39 in) high by 50–150 cm (20–59 in) across, with leaves to 80 cm (31 in) long.[4] The underside of the leaves and leaf edges are sharp and can easily cut human skin. The creamy flowers grow in spikes from the centre of the plant and appear from October to January. They are followed by shiny red or red-brown round nuts, which measure 4.5 to 6.0 mm long, 2.5 to 4.0 mm in diameter.[5]
Gahnia aspera is relatively easy to grow and benefits from a moist position in the garden for best foliage. It grows in semi-shade or some sun and has horticultural appeal in its foliage and nuts, but is not widely grown as propagation by seed is difficult. It also serves as shelter in the garden for small birds such as the superb fairywren.[4]
