Title: Low-growing lawn substitute for Pennsylvania
Answered by: Nan Hampton
Sedges look a lot like grass, but have the advantage of not growing very tall so that they do not need to be mowed. You can read about having a sedge lawn in John Greenlee's Sedge Lawns for Every Landscape. Here are several sedges that grow in Pennsylvania:
Carex blanda (eastern woodland sedge) sun, part shade, shade
Carex pensylvanica (Pennsylvania sedge) sun, part shade, shade
Carex texensis (Texas sedge) sun, part shade
The Brooklyn Botanic Garden has a good article by Claire Sawyers, Native Groundcovers—Low-Growing Herbaceous Plants for Sun and Shade Gardens, with suggestions of species that grow in Pennsylvania. Here are a few picks from her article:
Pachysandra procumbens (Allegheny-spurge) part shade
Phlox stolonifera (creeping phlox) sun, part shade, shade
Tiarella cordifolia (heartleaf foamflower) shade
Heuchera americana (American alumroot) sun, part shade, shade
Sibbaldiopsis tridentata (shrubby fivefingers) sun
Chrysogonum virginianum (green and gold) part shade
Low woody groundcover:
Gaultheria procumbens (eastern teaberry) part shade, shade
Ferns:
Polystichum acrostichoides (Christmas fern) sun, part shade
Dryopteris cristata (crested woodfern) sun, part shade, shade
You might consider mixing the ground covers depending on their tolerance for shade or sun.
