Acapulco Grass: A Mysterious Non-Native Perennial in Florida
If you’ve stumbled across the name Acapulco grass (Bouteloua dimorpha) in your gardening research, you’re likely dealing with one of the more enigmatic grass species in the southeastern United States. This perennial grass has established itself in Florida, though it remains something of a botanical mystery compared to its better-known cousins in the Bouteloua genus.
What is Acapulco Grass?
Acapulco grass is a perennial grass species that belongs to the Bouteloua genus, which includes many important native grasses throughout North America. However, this particular species stands out as a non-native introduction that has managed to establish populations in Florida, where it now reproduces on its own in the wild.
The plant was previously known by the scientific synonym Opizia stolonifera, which you might encounter in older botanical references. Despite its established presence, much about this grass remains poorly documented in horticultural literature.
Where You’ll Find It
Currently, Acapulco grass has been documented growing in Florida, where it has successfully established self-sustaining populations. Its common name suggests origins in the Acapulco region of Mexico, indicating it’s likely a tropical or subtropical species that found suitable growing conditions in Florida’s climate.

Should You Plant Acapulco Grass?
Here’s where things get a bit tricky. While Acapulco grass isn’t currently listed as invasive or noxious, its status as a non-native species that readily establishes in the wild raises some questions for environmentally conscious gardeners. The limited information available about this species makes it difficult to predict its long-term ecological impact or its garden performance.
Better Native Alternatives
If you’re drawn to the idea of adding a Bouteloua grass to your Florida landscape, consider these fantastic native options instead:
- Blue grama (Bouteloua gracilis) – A beautiful native bunch grass with distinctive curved seed heads
- Sideoats grama (Bouteloua curtipendula) – An attractive native grass with distinctive one-sided flower spikes
- Wiregrass (Aristida stricta) – A foundational species in Florida’s native ecosystems
The Bottom Line
While Acapulco grass might seem intriguing, the lack of detailed information about its growth habits, ecological impact, and garden performance makes it a questionable choice for most home gardeners. Florida offers an abundance of beautiful native grasses that are better documented, easier to source, and guaranteed to support local wildlife.
If you’re committed to including grasses in your landscape design, stick with well-researched native species that will provide reliable performance while supporting your local ecosystem. Your local native plant society or extension office can help you identify the best native grass options for your specific location and garden goals.
