- Description
-
Pennsylvania sedge is sedge in the Carex family native to thickets and dry woodland areas in North America. It is commonly found near oak trees, hence one of its common names "oak sedge". It grows in loose colonies and has a creeping habit with its reddish-brown roots.
It tolerates heavy shade and wet soils, though its ideal location is dry to moist shade. This plant is a good lawn substitute for shady areas but will not tolerate heavy foot traffic. It forms an ideal turf alternative in dry shade areas, needing mowing only once or twice a season to maintain a 2" height. It also makes a great underplanting for taller perennials. It is semi-evergreen, dying back under very cold temperatures. Identification of individual sedge (Carex) species can be difficult.
While it is native to NC, it tends to perform best in cooler climates.
Insects, Diseases, and Other Plant Problems: Smut, rust, and leaf spot are occasional problems along with aphids, Anthracnose, and Fungus gnat larvae.
