Carex laxiculmis (Spreading Sedge) is a small evergreen sedge forming dense, rounded mounds of narrow, arching, blue-green leaves to 12 in. long (30 cm). In late spring to early summer, it bears inconspicuous, creamy-white flowers atop triangular flowering stems. Native to rich wooded areas in eastern North America, Spreading Sedge can be used as an accent or ground cover in moist woodland gardens, shaded perennial beds or containers. It is a great choice for naturalizing since this species slowly spreads to form a fine-textured ground cover.

  • Grows easily about 6-12 in. tall and wide (15-30 cm). This plant will spread over time by rhizomes to form a dense ground cover.
  • Performs best in part shade to full shade in medium to wet soils. Soils should not be allowed to dry out.
  • Perfect plant for borders, woodland gardens, near ponds and streams, to edge paths or walkways and as a ground cover.
  • No serious disease or pest issues. Deer resistant.
  • Cut the foliage to the ground in late winter.
  • Propagate by seed or division.
  • Native to Canada, the central and southeastern United States.
