Shrub Carr Ecosystem-Soft Rush


Soft Rush

Order: Poales

Family: Juncacae

Genus: Juncus

Species: J. effuses

General Characteristics: Soft rush is a perennial wetland plant that grows in a clump or tussock and spreads by vigorous underground rhizomes. The bright green stems (there are no leaves) are cylindrical, without nodes, rather soft, and taper to a bristle. They are smooth or slightly striated. The clump is erect or slightly arching and usually stands a little less than 3 ft (0.9 m) tall. The flowers and fruits are borne in compact clusters that appear to emerge laterally a few inches below the tip of the flowering stem. Actually, the inflorescence emerges from the tip of the stem but a bract extends beyond and looks like a continuation of the stem.

Special Adaptations: Soft rush normally grows in areas that are periodically flooded. It grows best in such situations to be sure, but it also can withstand periods of drying out, and it can tolerate continued submergence in up to 3 in (7.6 cm) of water.
