Hairy-fruited Lake Sedge

About Hairy-fruited Lake Sedge

Hairy-fruited Lake Sedge (Carex trichocarpa) is a robust and aggressive perennial sedge designed for large-scale wetland stabilization and naturalization. Reaching heights of up to four feet, it features long, wide leaves and distinctive 'hairy' perigynia (seed coverings) that give the plant its name. This species is strongly rhizomatous, spreading quickly to form dense, expansive colonies that are excellent at outcompeting weeds and preventing erosion. Native to the northern and eastern United States, it is typically found in marshes, lake edges, and alluvial meadows. It thrives in full sun and wet to medium-wet soils, often forming the dominant cover in its preferred habitats. Because of its vigorous spreading habit, it is best suited for larger areas rather than small garden beds. Ecologically, it provides vast amounts of cover for wetland birds and amphibians and is a host plant for several species of sedge-boring moths. For those with ample space and a need for a tough, reliable wetland worker, Hairy-fruited Lake Sedge is an ideal candidate.
