Carex pensylvanica is a fine textured, cool season sedge for tough places like under Oak and Pine trees. Plants spread slowly by stolons and rhizomes to make a large colony. This makes it a great lawn substitute under Oaks and Pines or mixed between other plants in a shady garden to keep the weeds down. Tolerates very light foot traffic.

Maintenance: True low maintenance plant, may be mowed to a height of 3", one to three times a year. If doing this, the late winter mowing is the most important.

Benefits: Birds use prior seasons spent foliage as nesting material, deer resistant, juglone tolerant (Black Walnut)
