Common scouring rush is a spreading, reed-like perennial to 3 ft (0.9 m) tall. The evergreen stems are cylindrical, about 1/3 in (0.8 cm) in diameter, jointed, hollow, usually unbranched, and have rough longitudinal ridges. The tiny leaves are joined together around the stem, forming a narrow black-green band or sheath at each joint. Like other Pteridophytes (ferns and their relatives), scouring rush does not produce flowers or seeds.
