Sticky Lovegrass: A Tropical Grass for Warm Climate Gardens
If you’re gardening in the warmest parts of the United States and looking for a low-maintenance grass option, you might have encountered sticky lovegrass (Eragrostis glutinosa). This perennial grass has made itself at home in Puerto Rico and the U.S. Virgin Islands, though it’s not originally from these areas. Let’s explore what makes this grass tick and whether it deserves a spot in your landscape.
What is Sticky Lovegrass?
Sticky lovegrass is a perennial grass that belongs to the large and diverse lovegrass family. You might also see it listed under its former scientific name, Poa glutinosa. True to its common name, this grass has a somewhat sticky quality that sets it apart from other grasses in the landscape.
As a non-native species, sticky lovegrass has established itself successfully in tropical climates where it reproduces naturally without human intervention. While it’s not originally from the Caribbean region, it has adapted well to these warm, humid environments.
Where Does It Grow?
Currently, sticky lovegrass is found growing in Puerto Rico and the U.S. Virgin Islands. Its distribution is limited to these tropical locations, which gives us a big clue about its climate preferences.
Garden Appeal and Design Role
Like most lovegrasses, sticky lovegrass offers a fine-textured, naturalistic appearance that works well in informal landscape designs. Its perennial nature means it’ll return year after year, providing consistent ground coverage once established. The grass produces delicate, airy seed heads that add movement and texture to the garden.
This grass works best in naturalistic plantings where you want that wild meadow look rather than a formal, manicured appearance. It’s particularly useful for areas where you need reliable ground coverage without high maintenance requirements.
Growing Conditions and Care
Sticky lovegrass is only suitable for the warmest climates – think USDA hardiness zones 10-11. If you’re gardening anywhere that experiences frost, this isn’t the grass for you.
Based on its successful establishment in tropical climates, this grass likely prefers:
- Full sun to partial shade
- Well-draining soils
- Warm temperatures year-round
- Regular moisture, though probably drought-tolerant once established
The good news for busy gardeners is that sticky lovegrass appears to be relatively low-maintenance. Once it’s settled into your landscape, it should require minimal care beyond occasional watering during dry spells.
Should You Plant It?
Here’s where things get a bit complicated. While sticky lovegrass isn’t currently listed as invasive, it is a non-native species that has shown it can spread and establish itself without human help. This ability to naturalize means it could potentially outcompete native plants in some situations.
If you’re considering sticky lovegrass, you might want to first explore native grass alternatives that could provide similar benefits while supporting local ecosystems. Native grasses often offer superior wildlife benefits, including food sources for native insects and birds.
However, if you do choose to grow sticky lovegrass, monitor it carefully to ensure it doesn’t spread beyond where you want it in your garden.
A Word About Conservation
Interestingly, sticky lovegrass has a somewhat uncertain conservation status (listed as S2?, meaning undefined). This unusual situation – being both non-native and potentially of conservation concern – highlights the complex nature of plant conservation in our interconnected world.
The Bottom Line
Sticky lovegrass can be a useful addition to tropical gardens where you need reliable, low-maintenance ground coverage. However, given its non-native status and ability to spread naturally, consider native alternatives first. If you do plant it, enjoy its fine texture and easy-going nature, but keep an eye on its spread to be a responsible gardener.
Remember, the most sustainable landscapes are those that work with nature rather than against it, so native plants are usually your best bet for long-term garden success!
