Pennsylvania Sedge is lovely when planted on its own or to soften bed lines and walkways. When planted in groups or masses, its fine-textured, glossy, and bright green foliage creates a lush, undulating carpet. It can also be used for planting under larger plants such as Large White Trillium, Virginia Bluebells, Jacob’s Ladder, Allium, and Wisconsin Native Ferns, acting as a living green mulch to cover bare soil, fill in gaps, and suppress weeds. It’s an excellent choice for stabilizing sandy soils, their roots extend 1-2 feet, forming large colonies of underground rhizomes.
For those looking to replace a traditional turf lawn, Pennsylvania Sedge is a wonderful substitute when planted in drifts or masses, especially in shady areas where traditional grass struggles. Plant 12-inches apart to create a lawn that can be mowed to 3-inches or slightly lower, roughly 1 to 3 times a year. Thriving under oaks, hence its alternative name ‘oak sedge,’ plant in groups to light up the darkness with vibrant greenery and velvety texture.
