- Description
-
Pennsylvania sedge is 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 shade. This plant is a good lawn substitute but will not tolerate heavy foot traffic. It forms an ideal turf alternative in dry shade areas needing mowing only once or twice a sesaon to maintain a 2" height. Also makes a great underplanting for taller perennials. It is semi-evergreen, dying back under very cold temperatures. Idenfitification of individual sedge (Carex) species can be difficult.
Insects, Diseases, and Other Plant Problems: Smut, rust, and leaf spot, are occasional problems along with aphids, Anthracnose, Fungus gnat larvae.
