Prostrate Dallis Grass: A Lesser-Known Native Grass Variety
If you’ve stumbled across the name prostrate dallis grass (Paspalum dilatatum var. pauciciliatum) in your native plant research, you’re not alone in wondering what exactly this grass is all about. This particular variety of dallis grass is something of a botanical mystery, with limited information available even in specialized plant databases.
What We Know (And Don’t Know)
Prostrate dallis grass belongs to the grass family (Poaceae) and is classified as a variety of the more commonly known dallis grass (Paspalum dilatatum). You might also see it listed under its synonym Paspalum pauciciliatum. The prostrate in its common name suggests it has a low-growing, spreading habit, but beyond this basic classification, reliable information becomes scarce.
Here’s what makes this grass particularly challenging for gardeners: its native status, geographic distribution, growing requirements, and even its invasive potential remain largely undocumented in readily available sources. This lack of information raises some red flags for responsible gardeners.
The Geographic Mystery
Unfortunately, the specific geographic distribution of this variety is unknown, making it difficult to determine where it naturally occurs or whether it would be appropriate for your local ecosystem.
Should You Plant Prostrate Dallis Grass?
Given the limited information available, we’d recommend proceeding with caution. Here’s why:
- Unknown native status makes it impossible to verify if it’s appropriate for your region
- Lack of documented growing requirements means you’re gardening blind
- No information about invasive potential could lead to unintended consequences
- Limited availability suggests it may not be well-suited for typical garden settings
Better Native Grass Alternatives
Instead of taking a chance on this poorly documented variety, consider these well-researched native grass options that provide similar aesthetic appeal:
- Buffalo grass (Poikilacantha dactyloides) – excellent for dry, low-maintenance areas
- Blue grama (Bouteloua gracilis) – beautiful seed heads and drought tolerance
- Little bluestem (Schizachyrium scoparium) – stunning fall color and wildlife benefits
- Native sedges (Carex species) – grass-like appearance with proven ecological benefits
If You’re Still Curious
Should you encounter this grass variety through a reputable native plant source, make sure to:
- Verify its native status in your specific region
- Ask about its growth habits and potential spreading behavior
- Request information about its ecological benefits
- Understand its water and soil requirements
- Confirm it won’t become problematic in your area
The Bottom Line
While prostrate dallis grass might sound intriguing, the lack of reliable information makes it a risky choice for most gardeners. Your time and garden space are better invested in well-documented native grasses that offer proven benefits to both your landscape and local wildlife. When in doubt, stick with the tried-and-true natives that have comprehensive growing guides and established track records of success.
Remember, successful native gardening is about creating habitat and supporting local ecosystems – goals that are best achieved with plants whose characteristics and behaviors are well understood.
