Scirpus cyperinus

Woolgrass is not a true grass; it is actually a member of the sedge family. It is a coarse, densely clumped, native, perennial herb. Woolgrass has been used in restorations of wet meadows, sedge meadows, wet woodland reconstruction and peaty fens. It is an attractive plant for landscape design, mitigation and restoration sites. The short rhizomes help stabilize the soil. This species can be short-lived.
