Juncus effusus has a tight clumping growth habit and the stems are soft to the touch. Insignificant flowers appear along the side of the stem, below the stem tip. Prefers saturated soils or shallow water and is a good choice for the ornamental water garden. Slowly spreads rhizomatously.
In Japan, soft rush is grown to make tatami, which are woven mats used in the home. And up until the 1900s soft rush was used in England to make inexpensive lights called “rushlights.” The plant was soaked in animal fat then could be burned and used as a light.
