Sawbeak or Awl-fruit Sedge is an essential component in wetlands across much of the Pacific Northwest, where it establishes quickly to stabilize soil, host caterpillars and provide a larval food source for butterflies and moths. Its coarse leaves form dense tufts, while summer sprays of golden yellow seed heads feed songbirds and make this a prominent plant in moist, sunny landscapes.

Gardening with Sawbeak Sedge: This sedge will thrive in any full to part sun area with wet or boggy soils, such as a wet meadow, raingarden or moist, open woodland garden, where its sprawling rhizomes help to control erosion and stabilize banks. It tolerates seasonal flooding and requires summer water if planted in areas that become dry.
