Mountain Lovegrass: A Rare Hawaiian Native Worth Protecting

If you’re passionate about Hawaiian native plants, you might have come across mountain lovegrass in your research. This lesser-known perennial grass has a story that’s both fascinating and concerning – it’s a true Hawaiian endemic that’s becoming increasingly rare in the wild.

What Makes Mountain Lovegrass Special?

Mountain lovegrass (Eragrostis leptophylla) is one of Hawaii’s native grass species, belonging to the large and diverse grass family. As a perennial, it has the potential to be a long-lasting addition to appropriate landscapes, unlike many annual grasses that need replanting each year.

This grass is what botanists call an endemic species – meaning it exists naturally nowhere else on Earth except Hawaii. It’s found exclusively in the Hawaiian Islands, making it a true treasure of the Pacific.

The Conservation Reality

Here’s where things get serious: mountain lovegrass has a conservation status of S2S3, which places it somewhere between imperiled and vulnerable. This means the species faces real threats to its survival in the wild. For gardeners and native plant enthusiasts, this presents both an opportunity and a responsibility.

Should You Grow Mountain Lovegrass?

The short answer is: maybe, but with important caveats. Because of its rare status, this isn’t a plant you should casually add to your shopping list. However, if you’re committed to Hawaiian native plant conservation and have access to responsibly sourced material, growing mountain lovegrass could be part of conservation efforts.

Responsible Growing Considerations

If you’re considering growing mountain lovegrass, here are the key points to keep in mind:

  • Only source plants or seeds from reputable native plant societies, botanical gardens, or conservation organizations
  • Never collect from wild populations
  • Consider participating in organized conservation efforts rather than solo cultivation
  • Connect with local Hawaiian native plant groups for guidance

Growing Conditions and Care

As a Hawaiian mountain species, this grass likely prefers conditions that mimic its natural habitat. While specific cultivation information is limited, most Hawaiian mountain grasses tend to appreciate:

  • Well-draining soil conditions
  • Protection from extreme weather
  • Appropriate elevation and climate considerations for your location

Due to its specialized nature and conservation status, successful cultivation may require consultation with native plant experts familiar with Hawaiian grass species.

The Bigger Picture

Mountain lovegrass represents something larger than just another landscaping option. It’s a living piece of Hawaiian natural heritage that needs our protection. Whether you choose to grow it or simply learn about it, this grass serves as a reminder of the unique ecosystems that make Hawaii so special.

For most gardeners interested in supporting Hawaiian native plants, there are many other endemic species with more stable populations that might be better starting points. Consider exploring other native Hawaiian grasses and plants that can provide similar ecological benefits without the conservation concerns.

Getting Involved

If mountain lovegrass has captured your interest, the best way to support it might not be through individual cultivation. Consider connecting with:

  • Hawaiian native plant societies
  • Local botanical gardens with conservation programs
  • University extension programs focused on native plant preservation
  • Habitat restoration projects in Hawaii

Sometimes the greatest gift we can give a rare plant is to protect its wild habitat and support the scientists and conservationists working to ensure its survival for future generations.
