This attractive and very widely distributed sedge, grows in temperate areas, through much of the Northern Hemisphere to western South America, and in eastern and southern Africa, It can be found in a variety of habitats: along the stream margins and other wet areas, in depressions, pastures, etc. It generally reaches up to 1.5 m (4 ft.) in height and develops dense clusters of elegant, upright, green stalks with small yellowish green to light brown flowers. It grows well in USDA Zones 4 to 9 and thrives in wet soils, in full sun. Although it can be slow growing in the initial stage, once established it spreads quickly and its cultivation should be supervised, due to its invasive potential. In Japan, Juncus effusus is still commercially cultivated and used for making tatamis, a special type of woven mat.
