Leatherleaf Sedge Firefox (Carex buchananii 'Firefox') is grown for its coppery-bronze foliage that persists throughout much of the growing season. Its upright habit makes it a perfect fit for rock gardens and tight places in the landscape that could use a dose of earthy color. Leatherleaf Sedge 'Firefox' looks great on its own as a specimen or container plant, but shines when contrasted next to the deep greens of broadleaf shrubs like Boxwoods or purple leaved varieties such as Barberry's and Heuchera.
