Orchardgrass: A Hardy Perennial Grass for Your Landscape

If you’re looking for a tough, reliable grass that can handle a variety of conditions, orchardgrass (Dactylis glomerata glomerata) might catch your attention. This perennial grass has been making itself at home across North America for quite some time, and there are good reasons why it’s stuck around.

What Is Orchardgrass?

Orchardgrass is a robust perennial grass that forms dense, clumping tufts of blue-green foliage. Despite its name, you won’t find it growing apples—the orchard part comes from its historical use in European orchards as ground cover. This cool-season grass produces distinctive flattened flower heads that look a bit like a compressed bottlebrush, making it fairly easy to identify once you know what to look for.

The Not-So-Native Story

Here’s something important to know upfront: orchardgrass isn’t a North American native. Originally from Europe and temperate Asia, this grass has been introduced and now reproduces freely across an impressive range, from Alaska to Puerto Rico and pretty much everywhere in between. It’s established itself in all the lower 48 states, most Canadian provinces, and even made it to Hawaii and Greenland.

While orchardgrass isn’t currently classified as invasive in most areas, its non-native status is worth considering, especially if you’re passionate about supporting local ecosystems with native plants.

Why Consider Orchardgrass?

Despite being a non-native, orchardgrass does have some appealing qualities:

  • Extremely hardy and adaptable (USDA zones 3-9)
  • Excellent for erosion control on slopes
  • Thrives in challenging conditions where other grasses might struggle
  • Low maintenance once established
  • Forms attractive, dense clumps of foliage

Growing Conditions and Care

One of orchardgrass’s biggest selling points is its adaptability. This grass is remarkably unfussy about soil types and can handle both drought and moisture reasonably well. It prefers cool, moist conditions but won’t throw a tantrum if things get a bit dry.

For best results, plant orchardgrass in:

  • Full sun to partial shade
  • Well-draining soil (though it tolerates various soil types)
  • Areas where you want dense, clumping grass coverage

Planting and Establishment

Getting orchardgrass started is refreshingly straightforward. It’s typically grown from seed, which germinates readily in cool, moist conditions. Spring and early fall are the ideal planting times. Once established, this grass pretty much takes care of itself, requiring minimal intervention from you.

Landscape Uses

Orchardgrass works well in:

  • Meadow and naturalized garden settings
  • Erosion control areas
  • Low-maintenance landscape zones
  • Areas where you need reliable ground cover

Wildlife and Pollinator Considerations

As a wind-pollinated grass, orchardgrass doesn’t offer the nectar and pollen benefits that flowering native plants provide to bees and butterflies. However, like most grasses, it can provide some habitat and nesting material for various wildlife species.

Native Alternatives to Consider

If you’re drawn to orchardgrass but prefer supporting native ecosystems, consider these North American native grass alternatives:

  • Little bluestem (Schizachyrium scoparium)
  • Buffalo grass (Poaceae family natives)
  • Various native fescues specific to your region
  • Regional prairie grasses suited to your area

The Bottom Line

Orchardgrass is a reliable, low-maintenance option for specific landscape needs, particularly erosion control and naturalized areas. While its non-native status means it won’t support local ecosystems as effectively as native alternatives, it’s not currently considered problematic in most areas. If you decide to plant it, consider balancing it with native species elsewhere in your landscape to support local wildlife and pollinators.

As always, check with your local extension office or native plant society for the best grass recommendations specific to your region and garden goals.
