Carex pensylvanica

Oak Sedge, Pennsylvania Sedge

Carex pensylvanica, or Oak Sedge (or Pennsylvania Sedge) is found in dry woods mostly in Northeastern U.S. In North Carolina it occurs naturally in the mountain counties. This is one of the more popular sedges for gardeners and landscapers in our area because of its versatility. Plants are about 8 inches high (less than 12 inches when flowering), leaves are grass-like and delicate, and the habit is arching and graceful. Like many other sedges it grows well in part shade to full shade, but it stands out because it tolerates more sun (if moist) and spreads by rhizomes as well as by seed. It thrives as a living mulch under trees, shrubs and taller perennials. Pennsylvania Sedge can aslo be used as an alternative “No Mow” lawn to great effect, but it does not tolerate foot traffic. It prefers medium to dry soils, but because it can withstand wet conditions also, it is a good choice for rain gardens. It provides cover for small mammals and ground loving birds, and since it flowers and fruits early in the season before the warm season grasses, it is an early food source for a range of animals.
