gahnia sieberiana – Red-fruit saw-sedge

gahnia is a native tree with mostly large, robust sedges with long, arching leaves. The common name “saw edge” 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.
