Carex 'Blue Zinger' is a ornamental perennial sedge. A distinctive steel-blue sedge with narrow, arching, intensely blue-colored leaves. A striking color accent for mixed borders, containers, and shaded gardens. Adaptable to a wide range of conditions from moist shade to average borders. Largely evergreen and low maintenance. Cut back in late winter or early spring. Excellent for edging, woodland gardens, rain gardens, and containers where graceful, fine-textured foliage provides season-long interest.
