Cyperus ustulatus is a fast-growing sharp-edged swamp grass with olive-green leaves. Ideal for wetland and riparian revegetation. Taller plants may reach one metre high in fertile soil. This sedge is quick to colonize damp areas which will eventually establish tall swamp forests. The arching dark green foliage is complemented with green flowers in summer which age to a showy brown. Although we grow these in our water beds, they tolerate periods of dry. Commonly planted beside pools and riparian plantings.
