Slough Sedge

Slough sedge is a robust, rhizomatous, evergreen sedge native to wetlands, riparian areas, and wet meadows of the Pacific Northwest. It forms dense, tall clumps—often exceeding 3 feet in height—with narrow, arching leaves and nodding flower spikes that appear in spring to early summer. Highly tolerant of seasonal flooding and saturated soils, slough sedge spreads vigorously to create thick stands that stabilize streambanks, filter water, and provide excellent cover for fish, amphibians, and birds. Ecologically, it is a foundational wetland species, supporting biodiversity and improving habitat quality in riparian and marsh ecosystems.
