Juncus Effusus Spiralis is a perennial plant which forms a clump of dark corkscrewed and intertwined green stems. This attractive rush with its twisting leafless stems will make an unusual and quaint addition to your marginal pond planting. Small insignificant clusters of brown flowers may occasionally emerge from the sides of the foliage in summer. Juncus Effusus Spiralis is an evergreen plant, which means that the foliage of the plant persists and remains green throughout the year. Growth height up to 50cm (1.5 feet).
