Juncus articulatus is a species of rush known by the common names jointed rush and jointleaf rush. It is native to Eurasia and much of Canada and the United States. It grows in moist areas, such as wet sand, and thrives in calcareous soils. This is a perennial herb producing a mainly erect stem from a short rhizome. The stem may root at nodes, and it generally has one or more cylindrical leaves up to 10 centimeters long. The flower cluster atop the stem has several branches with up to 25 clusters of up to 12 flowers each. Each individual flower has greenish to dark brown, pointed petals 2 to 3 millimeters long, six stamens bearing anthers, and a protruding, feathery pistil. The fruit is a dark brown capsule with a pointed tip.
