Planting and Growing

Carex platyphylla, also called broad leaved sedge or silver leaved sedge, is a native sedge that prefers to grow in rich, moist deciduous forests or cove forests but can tolerate dry shade as it becomes more established. This shade-loving sedge does best in part-sun to full shade conditions and is an excellent choice for wooded gardens. This species is semi-evergreen with a silvery blue hue and typically forms clumps as it grows. Broad-leaved sedge is a host plant for many species of native skipper and wood satyr butterflies.

Carex platyphylla blooms with insignificant flowers in late spring, and is better suited to providing textural contrast in woodland gardens. Its semi-evergreen nature and low-growing habit make it an excellent choice for border plantings or interspersing among other taller shade perennials. Broad-leaved sedge typically grows around 8-12 inches tall and around a foot wide and is considered deer resistant.
