You’ve likely seen quite a few species of sedge in your time as a gardener. These attractive ornamentals get a lot of use as an alternative to ornamental grasses. Many ornamental grasses can require a lot of maintenance, and most require full sun. Sedge, on the other hand, is perfectly happy growing in partial shade. Some even prefer full shade conditions.
These useful landscaping plants serve more than one function in the garden. They are attractive as borders and look great lining a walkway. Use them as container plants, or choose a species that makes a good ground cover alternative. They are also great for preserving the soil and preventing erosion.
There are species of this plant that grow native to every continent except Antarctica. They adapt to many different climates and, once established, are exceptionally low maintenance. Making sure you’ve selected a sedge that will work in your space isn’t difficult. With close to 2,000 species and countless varieties, there is a beautiful sedge for every garden. Here are 21 of my favorite varieties.
Pennsylvania Sedge
Pennsylvania sedge is a great little variety that grows low to the ground. It makes an excellent grass alternative or ground cover. Requiring very little upkeep, this plant is wonderful for areas of the year that don’t get full sun. While most types of sedge are water-loving plants, this variety is surprisingly drought-tolerant. It will grow in a wide range of soil and moisture conditions.
This variety of sedges has white flowers that appear on spikes in the spring. Pollinators find it appealing, so it’s a great border for the pollinator garden. Avoid planting in areas that receive a lot of traffic, as the slender leaves don’t tolerate it well. This native of eastern and central North America is easy to grow and very cold hardy.
Blue Sedge
Blue sedge is a versatile beauty with thin, strap-like leaves in a blue-green shade. The underside of the leaves is gray, and the overall effect is cool and airy. This species is versatile. It can be drought tolerant and will spread more slowly this way. If you want your plants to grow more rapidly, give them more moisture, and they will take off.
This European native sedge is tolerant of different exposure conditions as well. It will grow fine in full sun as long as you give it plenty of moisture. In shadier situations, you are unlikely to have to give this plant much supplemental water. This type can also grow in boggy soil, and it stands up well to foot traffic.
Weeping Brown Sedge
This New Zealand native has a unique and interesting appearance. The long thin leaves are a soothing shade of brown with just the slightest hint of green toward the center. They arch gracefully toward the ground, making this a great plant to soften up parts of the landscape. Plant weeping brown sedge prefers to grow in full sun but will tolerate partial shade without any issues.
While weeping brown sedge will grow more rapidly in moist soil, it is quite drought-tolerant once established. It’s a mid-sized species with a height and spread of one to two feet tall and wide. This plant prefers warm and mild weather and won’t survive winters north of Zone 6. It looks great in a prairie garden or rock garden.
Orange New Zealand Sedge

Sand-Bracted Sedge
Sand-bracted sedge is a great variety for drier climates. It is among only a few truly drought-tolerant species and will thrive in sandy, dry soil quite nicely. Plant it in full sun or partial shade, adjusting watering to the location. A plant in full sun will need more water, but in general, this is a very low-maintenance species.
