Rush Carex pensylvanica

Other Common Name(s):

Description

Pennsylvania sedge is native to thickets and dry woodland areas in North America.  It is commonly found near oak trees, hence on of its common names "oak sedge".  It grows in loose colonies and has a creeping habit with its reddish brown roots.   Tolerates heavy shade and wet soils  though its ideal location is dry shade.   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) speices can be difficult.  

 

Insects, Diseases, and Other Plant Problems: Smut, rust, and leaf spot, are occasional problems. No serious insect or disease problems.
