Coconut Paspalum: A Rare Native Grass Worth Protecting in Your Garden
Meet coconut paspalum (Paspalum laxum), a delicate native grass that’s quietly making waves in coastal gardening circles. This unassuming perennial might not win any flashy flower contests, but it’s got something special—it’s a true native with an important story to tell.
What Makes Coconut Paspalum Special?
Coconut paspalum is a fine-textured, grass-like perennial that belongs to the true grass family. Don’t let its humble appearance fool you—this little grass is a botanical treasure that’s perfectly adapted to life in some of America’s most challenging coastal environments.
You might also see it listed under its scientific synonym, Paspalum glabrum, in older gardening references, but Paspalum laxum is the name that’s stuck.
Where Does Coconut Paspalum Call Home?
This charming grass is native to a surprisingly small area—just Florida, Puerto Rico, and the U.S. Virgin Islands. It’s what botanists call a narrow endemic, meaning it evolved to thrive in very specific conditions and doesn’t naturally occur anywhere else in the world.

Why You Might Want to Grow Coconut Paspalum
Here’s where things get interesting for native plant enthusiasts:

A Word of Caution: Rarity Matters
Before you rush out to find coconut paspalum, here’s something important to know: this grass has a Global Conservation Status of S3S4, which means it’s considered somewhat rare and potentially vulnerable. This doesn’t mean you shouldn’t grow it—quite the opposite! But it does mean you should be extra careful about sourcing.
Always purchase from reputable native plant nurseries that propagate their own stock rather than wild-collecting. Better yet, if you know someone who grows it responsibly, ask about getting seeds or divisions.
Growing Conditions: Keeping It Happy
Coconut paspalum is best suited for USDA hardiness zones 9-11, which makes sense given its tropical and subtropical native range. Here’s what it loves:
- Soil: Sandy, well-draining soils (think beach conditions)
- Sun: Full sun to partial shade
- Water: Moderate water needs; drought tolerant once established
- Salt tolerance: Excellent—this grass can handle coastal salt spray like a champ
Perfect Garden Spots
This grass shines in:
- Coastal restoration projects

Planting and Care Tips
The good news? Coconut paspalum is relatively low-maintenance once you understand its needs:
- Planting: Spring is ideal for establishment
- Watering: Water regularly during the first growing season, then back off
- Fertilizing: Usually unnecessary—this grass is adapted to nutrient-poor sandy soils
- Maintenance: Minimal pruning needed; let it grow naturally for best effect
The Bottom Line
