Carex pensylvanica, commonly called Pennsylvania sedge, is a shade-loving perennial sedge that is native to thickets and dry woodland areas in Eastern and Central North America. It typically grows in loose colonies with a creeping habit. Roots are reddish brown. It is often found in areas with oak trees, hence the additional common name of oak sedge. This is a low sedge with soft, delicate, arching, semi-evergreen leaves (each to 1/8" wide).
