Carex flacca (Blue Sedge)

Blue Sedge, Glaucous Sedge, Carnation Grass, Carex Glauca


Prized for its soft blue foliage, Carex flacca is a beautiful sedge forming a slowly spreading clump of narrow, arching leaves, blue-green above and glaucous-blue beneath. In early summer, it bears inconspicuous, slender, brown flower spikes, upright at first then slightly nodding over. Reminiscent of the garden carnation foliage, Blue Sedge is a great choice for naturalizing since this species spreads steadily to form a dense, fine-textured groundcover. Evergreen in warm winter climates

  • Grows easily about 6-12 in. tall (15-30 cm) and 12-18 in. wide (30-45 cm). This plant will spread over time by rhizomes to form a dense ground cover.
  • Enjoys full sun to part shade and thrives in medium to wet soils. Adaptable to a wide range of soils, including alkaline soils and can withstand some salinity. Drought tolerant. Can grow in standing water no deeper than 2 in. (5 cm).
  • Perfect plant for borders, woodland gardens, rock gardens, near ponds and streams, to edge paths or walkways and as a ground cover.
  • Deer tolerant and low maintenance.
  • Generally disease and pest free.
  • May be mown or clipped in early spring. Cut foliage to the ground and remove in late winter in cold winter climates
  • Clumps are easily divided in spring or early fall.
  • Native to the Mediterranean area
