Gahnia sieberiana – Red-fruit Saw Sedge

Gahnia is a native with mostly large, robust sedges with long, arching leaves. The common name ‘Saw Sedge’ refers to the rough edges of the leaves which can cause a painful cut if handled carelessly. They are usually found in damp areas or in areas subject to periodic inundation. For Australian gardens, Gahnia sieberiana has been suggested as a native replacement for pampas grass (Cortaderia selloana), which is a noxious weed there. It is a widespread plant that favours damp sunny sites. Many insect larvae have been recorded feeding on the Red-fruit Saw Sedge.
