The Challenge for Gardeners
Here’s where things get tricky for anyone considering this grass for their landscape: there’s remarkably little specific information available about Bothriochloa laguroides laguroides. Unlike many popular ornamental grasses, this subspecies hasn’t been widely studied or cultivated for garden use, leaving gardeners with more questions than answers about:
- Specific growing requirements
- Mature size and growth habits
- Aesthetic characteristics
- Potential benefits to wildlife and pollinators
- Appropriate USDA hardiness zones
A Word of Caution
Since this grass is documented as non-native in Hawaii and reproduces spontaneously in the wild, there are some considerations to keep in mind. While its invasive status isn’t clearly documented, any non-native plant that establishes itself in wild areas deserves careful consideration before introduction to new locations.
Consider Native Alternatives Instead
Given the limited information available about silver beardgrass and its non-native status, you might want to explore native grass alternatives for your region. Native grasses typically offer:
- Better adaptation to local climate conditions
- Established benefits for local wildlife
- Well-documented growing requirements
- Lower maintenance needs once established
- No risk of becoming invasive
Contact your local native plant society or extension office to learn about beautiful native grasses that would thrive in your specific area and provide known benefits to your local ecosystem.
The Bottom Line
While silver beardgrass might sound intriguing, the lack of available growing information and its non-native status make it a questionable choice for most gardeners. When in doubt, choosing well-documented native plants is usually the safer and more rewarding path for both your garden and the local environment.
