Wildlife and Ecosystem Benefits
While Houghton’s sedge is wind-pollinated rather than insect-pollinated, it still provides valuable ecosystem services.

This native sedge is an excellent choice if you’re looking for a low-maintenance, environmentally friendly groundcover that can handle challenging northern climates. It’s particularly well-suited for gardeners who appreciate subtle beauty over flashy blooms and want plants that support local ecosystems.
