Matojillo Bluestem: A Caribbean Native Grass Worth Growing
If you’re gardening in the Caribbean or other tropical regions, you might want to get acquainted with matojillo bluestem (Andropogon leucostachyus). This perennial grass is a true Caribbean native that brings both beauty and ecological value to the right garden setting.





What Makes Matojillo Bluestem Special?
Matojillo bluestem is a graminoid – that’s botanist-speak for a grass or grass-like plant. As a perennial, it comes back year after year, making it a reliable addition to your landscape. What sets this grass apart is its authentic Caribbean heritage and its ability to thrive in the unique conditions of tropical island environments.
Where Does It Come From?
This grass is a true native of the Caribbean region, specifically found growing naturally in Puerto Rico and the U.S. Virgin Islands. It’s perfectly adapted to island life, having evolved in these tropical environments over thousands of years.
Why Choose Matojillo Bluestem for Your Garden?
There are several compelling reasons to consider this native grass:
- Authentic native status: Supporting local ecosystems by choosing plants that naturally belong in your region
- Low maintenance: Once established, native plants typically require less water, fertilizer, and pest control
- Ecological benefits: Provides habitat structure for local wildlife and supports the natural food web
- Versatile growing conditions: Its facultative wetland status means it can handle both wet and dry conditions
Perfect Garden Settings
Matojillo bluestem shines in several landscape applications:
- Rain gardens and bioswales
- Coastal landscapes
- Naturalistic plantings
- Erosion control projects
- Native plant gardens
Growing Conditions and Care
This adaptable grass is well-suited to USDA hardiness zones 10-11, making it perfect for truly tropical climates. Here’s what matojillo bluestem prefers:
- Sunlight: Full sun to partial shade
- Soil: Tolerates various soil types
- Water: Moderate water needs; drought tolerant once established
- Maintenance: Low maintenance requirements
Planting and Care Tips
Getting matojillo bluestem established in your garden is relatively straightforward:
- Plant during the warm season when growth is most active

Is Matojillo Bluestem Right for Your Garden?
If you’re gardening in Puerto Rico, the U.S. Virgin Islands, or similar tropical climates, matojillo bluestem could be an excellent choice. It’s particularly valuable if you’re interested in native plant gardening, sustainable landscaping, or creating habitat for local wildlife.
However, if you’re outside of zones 10-11, this tropical grass won’t survive your winters. In that case, look for native grasses suited to your specific region – every area has its own wonderful native grass species that can provide similar ecological benefits.
For Caribbean gardeners, though, matojillo bluestem represents an opportunity to garden with nature rather than against it, creating beautiful landscapes that support local ecosystems while requiring minimal inputs from you.
