Gahnia aspera

Gahnia aspera known as the rough saw-sedge or round sawsedge is a tussock forming perennial plant, often seen in moist situations.

[4] The underside of the leaves and leaf edges are sharp and can easily cut human skin.

[5] It is found in a variety of situations, from rainforest to drier inland areas such as Rankins Springs and the Pilliga Scrub district in New South Wales.

[8] 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.
