A large sedge that forms big clusters of sharp-edged, arching, narrow leaves to about 2 m tall. The tall, dark inflorescences stand above the leaves. Native to southeastern Australia and Tasmania it grows in a variety of habitats, usually on wet or even swampy ground. It is an impressive, ornamental grass for cool to warm temperate regions and the inflorescences are popular for flower arrangements. Seeds are somewhat lengthy to germinate and can take over a year to sprout.
