Sedges are grass-like plants belonging to the genus Carex—and there are so many reasons they make a great addition to a garden.

They are versatile and gorgeous, adding height, texture, and movement anywhere you plant them. Many people plant sedge grass because it is low-maintenance and has a beautiful range of colors, from green and yellow hues to purple and red. With over 2,000 species, you can find sedge grass varieties for almost every type of garden and climate. They are often drought-tolerant, making them a great choice for more arid climates.

"Thanks to the diversity of habitats in which Carex are found in the wild, from mountain tops to coastal dunes, there is a Carex for nearly every garden condition imaginable," says Sam Hoadley, Manager of Horticultural Research at Mt. Cuba Center.

Sedge grass is often planted as a ground cover, used in rain gardens, as a border, and as a substitute for lawns, both mowed and unmowed. And planting sedges native to your region offers a boost to biodiversity. "Their leaves are the food sources for caterpillars of several species of butterflies and moths, their seeds are eaten by a variety of birds and small mammals, and Carex themselves provide shelter to a diversity of animals," says Hoadley. 

With all these perks, it's no wonder these grass-like plants are so beloved by gardeners! Ready to dive into the world of sedges? Here are 10 varieties native to the United States that experts recommend.

Looking for a sedge grass to grow in the shade? Consider Pennsylvania sedge. "It is a wonderful companion to other plants in both shade and sun and will slowly spread by rhizomes to weave a groundcover under its taller neighbors," says Hoadley. The narrow leaves or blades are deep green and grow about 12 inches high.

If you want to reduce or eliminate your lawn, this sedge grass makes a great alternative. "In a garden bed, this can reduce or eliminate the need to apply seasonal mulch, and this species can even be used as a turfgrass lawn substitute, especially in dry shade," says Hoadley.

  • Zone: 3 to 8
  • Height: Up to 12 inches tall
  • Light: Full shade to full sun

Appalachian sedge, or Carex appalachica, has fine, slender leaves and is commonly found in the wild in the Appalachian Mountains. Because this sedge thrives in the shade, this makes a wonderful ground cover under trees or any area on your property that doesn't receive much or any sun. You can also grow it in containers or use it as a border, such as planting along a walkway. "Carex Appalachia is well equipped to grow in rocky soils with excellent drainage but will be happy in cultivation as long as the soils aren’t too wet," says Hoadley.

  • Zone: 3 to 7
  • Height: up to 12 inches
  • Light: shade or sun
