Bristly Lovegrass: A Lesser-Known Non-Native Grass

If you’ve stumbled across the name bristly lovegrass while researching grasses for your garden, you’ve discovered one of the more mysterious members of the grass family. Known botanically as Cladoraphis cyperoides, this perennial grass species has a rather enigmatic presence in North American gardening circles.

What Exactly Is Bristly Lovegrass?

Bristly lovegrass is a perennial grass that belongs to the broader category of graminoids – that’s garden-speak for grasses and grass-like plants. While it might sound like it should be native to North America, this species is actually non-native and has been introduced to our ecosystems. It has managed to establish itself and reproduce on its own in the wild, which puts it in the category of naturalized plants.

The plant has some interesting taxonomic history, having previously been classified under different names including Eragrostis cyperoides and Poa cyperoides. These name changes aren’t uncommon in the plant world as scientists continue to study relationships between species.

Where Does It Grow?

Currently, bristly lovegrass has been documented growing in Oregon, making it quite geographically limited in its North American presence. This limited distribution suggests it hasn’t become widespread across the continent.

The Mystery Factor

Here’s where things get interesting – and a bit frustrating for gardeners seeking information. Bristly lovegrass falls into that category of plants where detailed growing information, care requirements, and ecological impacts are poorly documented or unknown. We don’t have clear information about:

  • Specific growing conditions it prefers
  • USDA hardiness zones
  • Mature size and growth habits
  • Wildlife or pollinator benefits
  • Whether it has invasive tendencies
  • Propagation methods

Should You Plant It?

Given the limited information available about bristly lovegrass, it’s difficult to make strong recommendations either for or against planting it. While it’s not currently listed as invasive or noxious, the lack of comprehensive ecological data means we can’t fully assess its potential impact on local ecosystems.

For most gardeners, this uncertainty makes bristly lovegrass a less attractive choice compared to well-documented native grasses that provide known benefits to local wildlife and ecosystems.

Better Native Alternatives

Instead of taking a chance on this mysterious grass, consider these well-documented native alternatives that provide excellent benefits for wildlife and are easier to grow successfully:

  • Little bluestem (Schizachyrium scoparium) – beautiful fall color and excellent for birds
  • Buffalo grass (Bouteloua dactyloides) – drought-tolerant and low-maintenance
  • Blue grama (Bouteloua gracilis) – graceful seed heads and wildlife-friendly
  • Sideoats grama (Bouteloua curtipendula) – distinctive seed arrangement and good for erosion control

The Bottom Line

While bristly lovegrass might intrigue plant collectors or those interested in unusual species, the lack of available growing information makes it a challenging choice for most gardeners. Native grasses offer more predictable results, better-documented care requirements, and known ecological benefits.

If you’re set on growing less common grasses, focus on native species that might be underutilized in gardens rather than non-native species with unknown ecological impacts. Your local native plant society or extension office can help you discover native grasses that might be perfect for your specific growing conditions and gardening goals.
