Remy’s Sandmat: A Rare Hawaiian Native Worth Protecting
If you’re passionate about Hawaiian native plants and conservation gardening, you may have heard whispers about Remy’s sandmat (Chamaesyce remyi var. remyi). This unassuming little shrub might not win any flashy flower contests, but it holds a special place in Hawaii’s botanical heritage—and it desperately needs our help.
What Makes Remy’s Sandmat Special?
Remy’s sandmat is a perennial shrub that’s as Hawaiian as it gets—this plant is found nowhere else on Earth except in the beautiful islands of Hawaii. It’s what botanists call endemic, meaning it evolved here and calls these islands its one and only home.
This modest plant typically grows as a multi-stemmed woody shrub, usually staying under 13-16 feet tall, though it often grows much smaller. Don’t expect towering grandeur from this one—Remy’s sandmat is more about understated charm and ecological importance than showy display.
The Reality Check: This Plant is Rare
Here’s where things get serious, fellow gardeners. Remy’s sandmat has a Global Conservation Status of S1T1, which essentially means it’s extremely rare and vulnerable. This isn’t a plant you’ll find at your local nursery, and that’s probably for the best.
If you’re considering adding this species to your garden, please—and we cannot stress this enough—only work with responsibly sourced material from reputable native plant organizations or botanical institutions. Wild collection is absolutely not okay for a plant this rare.
Growing Conditions and Care
Should you be fortunate enough to obtain Remy’s sandmat through proper conservation channels, here’s what you need to know:
- Climate: Thrives in USDA hardiness zones 10-12 (tropical and subtropical)
- Sunlight: Prefers full sun to partial shade
- Soil: Well-draining soils are essential—this plant doesn’t like wet feet
- Water: Drought tolerant once established, but may need regular water during establishment
- Wetland status: Classified as Facultative Upland, meaning it usually grows in non-wetland areas but can tolerate some moisture
Garden Role and Landscape Use
In the right setting, Remy’s sandmat can serve as an excellent ground cover or low shrub for native Hawaiian landscapes. It’s particularly valuable for:
- Native habitat restoration projects
- Drought-tolerant landscape designs
- Coastal gardens (where appropriate)
- Educational gardens focused on Hawaiian flora
This isn’t a plant for every garden—it’s more of a conservation statement piece that shows your commitment to preserving Hawaii’s unique botanical heritage.
The Conservation Gardener’s Perspective
Should you plant Remy’s sandmat? Only if you can do so responsibly. This rare native deserves our respect and protection, not casual cultivation. If you’re passionate about supporting Hawaiian natives, consider these approaches:
- Connect with local native plant societies and conservation organizations
- Support botanical gardens and research institutions working with rare Hawaiian plants
- Focus on more readily available Hawaiian natives for your everyday gardening
- Volunteer for habitat restoration projects where this species might naturally occur
The Bottom Line
Remy’s sandmat represents something precious: a piece of Hawaii’s evolutionary story that exists nowhere else on our planet. While most of us won’t be growing this rare beauty in our backyards, we can all play a role in ensuring it doesn’t disappear forever.
If you’re drawn to Hawaiian native plants, there are many other wonderful endemic species that are more readily available and equally deserving of our gardening attention. But keep Remy’s sandmat in your thoughts—and maybe your donations—as a reminder of what we stand to lose if we don’t take plant conservation seriously.
After all, some plants are worth more in the wild than in our gardens, and Remy’s sandmat is definitely one of them.
