Narrow-leaved Cotton Grass

About Narrow-leaved Cotton Grass

Narrow-leaved Cotton Grass, also known as Tall Cottonsedge, is an iconic wetland plant that brings a touch of the arctic tundra to northern bogs and water gardens. This grass-like perennial typically grows 1 to 3 feet tall, featuring slender, upright leaves that provide a clean, vertical accent. In early summer, it produces multiple drooping flower spikes that eventually transform into fluffy, pure white cottony heads. These soft, silken seed heads are truly distinctive and remain attractive for several weeks, swaying beautifully in the breeze. Native to cold bogs, fens, and wet meadows across the northern United States and Canada, it is a specialist that thrives in full sun and acidic, saturated soils. Ecologically, it provides important cover for waterfowl and is a food source for various small mammals. For the home gardener, it is a spectacular choice for the edge of a pond or a dedicated bog garden where consistent moisture is available. Its unique appearance and exceptional cold-hardiness make it a standout specimen for specialized native plantings.
