45 Ornamental Grasses Native to the United States
Are you looking for an ornamental grass to enhance your landscape? There are a multitude of beautiful, interesting, and hardy ornamental native grasses to choose from. In this article, gardening expert Liessa Bowen introduces 47 fantastic native grass species that make excellent landscaping plants.
Contents
Grasses are a unique grouping of flowering plants belonging to the family Poaceae. Worldwide, they are common and diverse.
Grasses may be annual or perennial and warm-season or cool-season. There is an immense range of sizes, ranging from tiny ground-hugging plants only a few inches tall to giant bamboo that grows to almost 100 feet tall.
In the United States, grass species inhabit almost every ecosystem. Some native species are spectacularly showy, while others are more subtle. But it’s good to know that no matter where you live, you can find native grasses that will enhance and beautify your landscape.
Here are just a few of the benefits of growing native ornamental grasses:
- Showy and attractive foliage and flowers that provide year-round interest
- Excellent for erosion control and soil stabilization
- Many are drought-resistant or water-loving and will grow where other plants won’t
- Provide valuable wildlife habitat and attract foraging birds with their seeds.
You must consider a few things when choosing the best ornamental grass for your landscape. Look at the USDA plant hardiness zone map and identify your zone. Make note of your available sunlight, soil type, and soil moisture, and choose well-matched plants for your local growing conditions. Finally, you’ll want to be sure that the plants you choose will have enough space to grow in your landscape arrangement.
Let’s now dig a little deeper into some specific native ornamental grass species that you can grow at home!

Wiregrass is an attractive clump-forming rush native throughout North America. This common, widespread rush is easy to grow in any sunny site with moist to wet soil. It is particularly well adapted to growing in and around wetlands and makes an excellent plant for erosion control.
This grass produces dense clusters of thin, tubular, straight stems. It blooms in the summer with greenish-brown flowering bracts. When planted en masse, wiregrass can be mowed high to make a satisfying lawn substitute in wetter areas. Wiregrass tends to grow quickly and aggressively, so be sure to plant this in a location where it can spread freely and not become a nuisance.

Frequently Asked Questions
Do I need to mow ornamental grasses?
Most ornamental grasses don’t need to be mowed like the standard turfgrass in your lawn. You should, however, cut back your ornamental grasses once each year. This will help them continue to look great and also allow them to grow freely without fighting their way through a mass of dead vegetation each year.
The best time to cut back is in the early spring. Leave your ornamental grasses standing during the winter. This provides food for foraging birds, shelter for a variety of small wildlife, and simply keeps your yard looking interesting during the winter months. Then in the early spring, use a set of large, sharp pruning shears to give your grass a haircut to allow plenty of space for fresh new growth.
My ornamental grass has grown really big! Can I divide it?
If your ornamental grass grows large enough, you’ll probably want to divide it. Division of mature clumps is an excellent way to keep growth in check and create new clumps to transplant or share with your gardening friends.
Dividing is simple. In late winter or early spring, ideally before new growth begins, dig up the entire clump of grass. Using a sharp spade, divide the clump into two or more separate clumps. Each freshly divided clump can then be transplanted anywhere you want more ornamental grasses! Be sure to allow each clump plenty of space to grow to its full size in a new location.
Can I grow ornamental grasses in containers?
Yes! Many native grasses, especially those that are drought tolerant, are excellent candidates for container gardening. Since grasses can grow into rather large clumps, you’ll want to choose a larger container to accommodate them. A single cluster of ornamental grass in a large container, however, can create a spectacular display!
You may want to grow just one grass plant per container so it can spread and fill the space. Unless your container is very large or your grass is very small, it will be difficult to grow ornamental grasses in a small space alongside other plants because the grasses will want to dominate the available space. Growing ornamental grasses in containers is also a great way to control species that spread rapidly.
What other plants grow well with ornamental grasses?
Since ornamental grasses tend to be large and clump-forming, they won’t resemble the grass species in your lawn, and you won’t treat them the same. Instead, you will probably treat ornamental grasses more like a perennial wildflower or a small shrub.
Clump-forming ornamental grasses make excellent accent plants in the landscape. They can be grown alongside other grassland plants to create a natural habitat. But they can also grow very well alongside shrubs and wildflowers, as long as you choose plants that all thrive in similar growing conditions. Grasses, forbs, and shrubs each have unique vegetation, flowers, and growth forms, so can complement each other well to create an interesting and diverse landscape.
Final Thoughts
No matter where you live, there are native ornamental grasses to suit your landscaping needs. Native grasses are easy to grow, hardy, and interesting to look at. They can be used in various gardening styles, from pocket prairies to habitat restorations to stand-alone accent plants. Native grasses can be small and compact or large and very showy, and many attract birds, small wildlife, and beneficial insects.
