This is an evergreen water-loving, attractive, medium-sized groundcover that grows to 30cm high and 15cm wide. It has very inconspicuous leaves, represented by red-brown sheaths at the base. It should be planted in full sun. It is an excellent plant for the containers and is ideal for small wetland gardens. The name is derived from Latin ‘cuperos’ and Greek ‘kypeoros’= sedge or rush.
