Tesselaar markets Everest Carex (Japanese sedge). Initially released with the Novalis “Plants that Work” group in 2010, Carex oshimensis Everest is now available to all growers nationally. With its bright-white margins and architectural, linear foliage, Everest is stunning as a container and patio plant or as a filler with bedding and specimen plants. A shade-lover, Everest also brightens up any dark area, and its low-growing, easily controlled, mounding form softly edges any border or bed.
