Spike rush is a wetland plant characterized by its green, leafless stems that range in height from 5 inches to 4 feet. It grows in clumps and is easily recognized by the small brown spikelets at the tip of each stem. Typically found along shorelines and in shallow water, spike rush plays an important role in stabilizing soil and providing habitat for aquatic wildlife. While beneficial for erosion control, it can spread aggressively in some environments, sometimes requiring management to maintain balanced aquatic and shoreline ecosystems.
