Juncus effusus is a cosmopolitan rush species that occurs in most temperate world regions, including North America, Europe and Asia; moreover, the plant also can be found in many montane-tropical regions. Also Known as Soft rush, the clumping plant manifests stout but supple stems that may reach 1.5 meters in height. Habitats are diverse, but often feature moist areas at forest margins, wet grasslands, wetland margins, lake shores, river banks, and in fen-meadows.
