description_en: Genus of about 300 species of grass-like, hairless, evergreen or deciduous, rhizomatous perennials, widely distributed throughout the world, but mostly occurring in cool-temperate regions, particularly in heavy, wet, acid soil. The stems are cylindrical, nodeless, and usually solid, and the leaves, when present, are small and narrow, often reduced to basal sheaths. Unlike grasses and sedges, rushes produce small green or brown flowers with 6 tepals, borne in cymes in midsummer. Ornamental forms include cultivars with twisted or variegated stems. Rushes are suitable for a pond side or bog garden, but some will also thrive in moist garden soil.
