Crested Wheatgrass: A Hardy Non-Native Grass for Challenging Sites
If you’re dealing with a tough spot in your landscape where nothing seems to want to grow, crested wheatgrass (Agropyron cristatum) might just be the solution you’re looking for. This perennial grass has earned a reputation as one of the most resilient plants you can grow, though its non-native status means it comes with some considerations worth discussing.
What is Crested Wheatgrass?
Crested wheatgrass is a cool-season perennial grass that forms attractive bluish-green clumps with distinctive feathery seed heads that give it its crested name. Originally from Asia and parts of Europe, this hardy grass has become widely established across North America, from Alaska down to Texas and from coast to coast.
As a graminoid (grass-like plant), it produces the characteristic narrow leaves and wind-pollinated flowers typical of the grass family. What sets it apart is its remarkable ability to thrive in conditions that would leave other plants struggling.
Where Does It Grow?
Crested wheatgrass has an impressive geographical range, growing successfully in dozens of states and provinces across North America. You’ll find it established in Alberta, British Columbia, Alaska, Manitoba, California, Nova Scotia, Ontario, Colorado, Connecticut, Quebec, Delaware, Saskatchewan, Yukon, Northwest Territories, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wyoming, and Labrador.
This widespread distribution speaks to its adaptability, but it’s important to remember that as a non-native species, it reproduces spontaneously in the wild and tends to persist without human intervention.
Should You Plant Crested Wheatgrass?
The answer depends on your specific needs and gardening philosophy. Here are some reasons you might consider it:
- Exceptional drought tolerance once established
- Thrives in full sun and well-drained soils
- Excellent for erosion control on slopes and challenging sites
- Hardy in USDA zones 3-8
- Low maintenance requirements
- Forms attractive clumps with interesting seed heads
However, since it’s not native to North America, you might want to consider native grass alternatives that provide similar benefits while supporting local ecosystems. Native options like buffalo grass, blue grama, or little bluestem can offer comparable drought tolerance and erosion control while providing better habitat for native wildlife.
Growing Conditions and Care
If you decide crested wheatgrass fits your needs, you’ll find it refreshingly easy to grow. This grass prefers full sun and well-drained soils but isn’t particularly picky about soil type. It’s remarkably drought tolerant once established, making it perfect for xeriscaping projects or areas with limited irrigation.
The grass forms dense tufts that can help prevent soil erosion, making it valuable for restoration projects and challenging slopes. While it doesn’t offer significant benefits to pollinators (being wind-pollinated), it can provide some habitat structure in naturalized areas.
Planting and Care Tips
Getting crested wheatgrass established is straightforward:
- Plant seeds in fall or early spring when soil temperatures are cool
- Prepare the seedbed by removing competing vegetation
- Sow seeds at a rate of 8-12 pounds per acre for large areas
- Lightly rake seeds into soil (they need good soil contact but shouldn’t be buried deeply)
- Water regularly until germination occurs
- Once established, it requires minimal care and irrigation
The grass is quite forgiving and doesn’t require fertilization in most soils. Its deep root system helps it access water and nutrients efficiently.
The Bottom Line
Crested wheatgrass is undeniably tough and useful for challenging sites where erosion control and drought tolerance are priorities. While it’s not native, it’s not typically considered invasive either. If you choose to plant it, consider using it in restoration projects or utility areas rather than prime garden spaces where native alternatives might serve both your needs and local wildlife better.
Remember, the best landscaping choices often balance practical needs with ecological stewardship. Whether you choose crested wheatgrass or a native alternative, you’re taking a positive step toward creating a more resilient landscape.
