Pennsylvania sedge produces leaves up to 2 ft (0.6 m) long and 1 to 3 mm (0.04 to 0.12 in) wide that become arching at maturity. It has culms (stems) 10 to 45 cm (4 to 18 in) long.
Pennsylvania sedge blooms early in the spring, from April to June. Each flower cluster contains one slender staminate (male) spike 10 to 25 mm (0.39 to 0.98 in) long above one to three shorter pistillate (female) spikes each with 4 to 12 florets. During the blooming period, the staminate spike produces slender cream-colored anthers, aging to light brown, and each pistillate floret produces three long white, thread-like styles. The scales underneath the florets are dark purple.
Ecology
This competitive species is often found in large monotypic stands. It is mainly vegetative, spreading via systems of cordlike rhizomes. Shorter rhizomes produce tufts, clumps, and mats, and longer rhizomes form wide, matted colonies.
