Prieur’s Umbrellagrass: An Uncommon Non-Native Grass Worth Knowing About
If you’ve stumbled across the name Prieur’s umbrellagrass (Enteropogon prieurii), you’re likely dealing with one of the more obscure grasses in North American flora. This annual grass might not be the showstopper you’re looking for in your garden, but understanding what it is—and why you probably shouldn’t plant it—is worth your time.
What Is Prieur’s Umbrellagrass?
Prieur’s umbrellagrass is a non-native annual grass that has established itself in parts of the southeastern United States. Originally described under the scientific name Chloris prieurii, this grass belongs to the diverse world of graminoids—plants that include true grasses, sedges, and rushes. As an introduced species, it reproduces on its own in the wild without human assistance, which means it’s naturalized in its adopted home.
Where You’ll Find It
Currently, Prieur’s umbrellagrass has been documented growing in Alabama and North Carolina. Its limited distribution suggests it hasn’t become widespread across the continent, though this could change over time as climate and land use patterns shift.

Should You Plant Prieur’s Umbrellagrass?
Here’s where things get interesting—and a bit problematic. While this grass isn’t currently listed as invasive or noxious, there’s remarkably little information available about its garden performance, growing requirements, or ecological impact. This lack of documentation is actually a red flag for gardeners who want to make informed choices.
As an annual grass, Prieur’s umbrellagrass completes its entire life cycle in one growing season, which means you’d need to replant it yearly or rely on self-seeding. Without knowing its growth habits, mature size, or aesthetic qualities, it’s impossible to recommend it for any specific garden application.
Better Alternatives: Native Grasses That Deliver
Instead of taking a chance on this poorly-documented species, consider these native alternatives that offer proven performance:
- Little bluestem – A beautiful bunch grass with stunning fall color
- Buffalo grass – Perfect for low-maintenance lawns in appropriate climates
- Switchgrass – Excellent for prairie gardens and wildlife habitat
- Purple lovegrass – Adds delicate texture and movement to garden beds
The Bottom Line
While Prieur’s umbrellagrass isn’t necessarily harmful, it’s not particularly helpful either. With so many well-documented native grasses available that provide clear benefits to pollinators, wildlife, and garden aesthetics, there’s little reason to seek out this obscure species for cultivation.
If you encounter Prieur’s umbrellagrass in the wild, it’s worth noting its presence—especially if you’re outside its known range in Alabama and North Carolina. But for your garden? Stick with the natives that we know will support local ecosystems while giving you the beauty and performance you’re looking for.
Remember, every plant choice is a vote for the kind of landscape you want to create. Make yours count by choosing species that contribute positively to your local environment while meeting your gardening goals.
