This evergreen groundcover grows to 1.5m high and 1m wide. It is an attractive accent plant for a dam or pond. It forms a clump of bare stems, each topped by a rounded head of narrow spiky leaves. The stems are used to make traditional sleeping mats, baskets and twine. It is frost resistant with brownish flowers in summer. Plant it in the sun or semi-shade in a wetland or next to a water feature where it will get sufficient water. It attracts birds which use it for nesting. The name is derived from Latin ‘cuperos’ and Greek ‘kypeoros’= sedge or rush.
