Carex Flacca 'Blue Zinger'
Blue Sedge, Heath Sedge
Carex flacca ‘Blue Zinger’ is a cool-season, semi-evergreen sedge valued for its soft blue-gray foliage and spreading, groundcover habit. Narrow leaves emerge silvery-blue in spring, form low, flowing clumps that gradually spread by rhizomes through the growing season, and remain attractive into fall, while small, inconspicuous flower spikes appear in spring. Its cool-toned color and adaptability make it useful for edging, mass plantings, and erosion control.
