The Low-Maintenance Grass Alternative Perfect For Your Shady Yard

More and more gardeners are interested in eliminating some or all of the turfgrass on their properties and instead using native and ornamental grasses, among other plantings. If you're one of them and are feeling limited because your yard is shady, consider the native grass Pennsylvania sedge (Carex pensylvanica), also known as oak sedge because it often grows near oak trees. Pennsylvania sedge is one of over 1,500 species of Carex, considered the sustainable grass alternative landscaping experts swear by for your home lawn. This sedge loves moderate to heavy shade and makes a great lawn alternative. 

Its delicate, grassy foliage arches and billows into a fountain-like shape that grows 6 to 8 inches tall. Flowers bloom on Pennsylvania sedge in late spring, but they are unremarkable. The foliage turns light brown in the fall. Best of all, this herbaceous perennial is easy to maintain, especially for those who don't like to mow; this sedge needs only one or two mowings per season if you want to maintain a lower height. It's hardy in USDA Hardiness Zones 3 to 8, but struggles south of Zone 8.

Pennsylvania sedge is deer-resistant and drought-tolerant once established, which adds to its low-maintenance qualities. Plus, it can draw wildlife to your yard. For both habitat and seeds, birds are attracted to this sedge, which also supports several species of moths and butterflies. Pennsylvania sedge is not for areas with heavy foot traffic or wet soil, though. While it can tolerate wet soil, it prefers dry to moist areas. The plants spread via rhizomes, but are not considered invasive.

When choosing the location for your Pennsylvania sedge, avoid areas with full sun — the plant wants at least dappled shade and can even tolerate heavy shade. Plant your Pennsylvania sedge in well-drained, dry to medium, regular garden soil. Growing this type of sedge from seed is not recommended as it typically doesn't grow well; instead, use plugs and place them about 6 to 12 inches apart to give them room to expand. Remove any established perennial grasses from the site before planting. You can plant in fall, late winter, or early spring. 

If you're looking to cover an area with the plant, expect to wait two seasons for full coverage with Pennsylvania sedge, which will ultimately provide a soft, carpet-like effect. Expect the plants to die back in cold weather. Consider Pennsylvania sedge as part of your plan to grow a gorgeous, healthy shade garden. Try planting this sedge under tall perennials. Once you know all of the advantages to growing ornamental grasses in your yard and garden, you'll want to bring as many native and ornamental grasses as you can to your garden.
