Carex Speciosa
Speciosa Grass
Carex siderosticha ‘Variegata’, often sold as Carex speciosa, is a low-growing, cool-season sedge valued for its broad, bamboo-like foliage marked with creamy-white variegation. Leaves emerge fresh green with bright white margins in spring, form a spreading, groundcover-like clump through the growing season, and remain attractive into fall, while small, inconspicuous flower spikes appear in spring. Its bold foliage and shade tolerance make it an excellent choice for brightening woodland gardens and shaded borders.
