Pennsylvania Sedge is a native, shade loving perennial. The foliage is narrow, shiny, bright green and appears in loose clumps. The leaves are also semi-evergreen, and provide some winter interest.
This plant works best as a ground cover in a shaded area or mass planted as a substitute for a lawn that doesn’t need regular mowing. It can spread to create small colonies through underground rhizomes. This Carex is naturally found in open forests, shaded bluffs and slopes, or oak savannahs (thus the common name, "Common Oak Sedge"). Pennsylvania Sedge can tolerate some sun and dry conditions, but typically grows best with partial shade and regular moisture.
