Comments: a common woodland sedge that can be easily confused with other woodland sedges. One sedge that comes in looking a lot like like Pen sedge is Carex communis. Pen sedge differs in having long rhizomes that spread horizontally. Usually Pen sedge flowers earlier than C. communis.
Etymology: The genus Carex comes from the Latin word meaning "reed-grass". The specific epithet, pensylvanica, simply means, "of Pennsylvania".

Landscape: for a native, sedgy lawn, this is the plant for you. It is the best substitute for that pesky lawn grass.
