Remy’s Sandmat: A Critically Rare Hawaiian Treasure Worth Protecting
Meet Remy’s sandmat (Chamaesyce remyi var. kauaiensis), one of Hawaii’s most endangered native plants. This remarkable little shrub represents both the incredible biodiversity of the Hawaiian Islands and the urgent need for plant conservation in our modern world.
What Makes This Plant Special?
Remy’s sandmat belongs to the Chamaesyce genus and is scientifically known by its synonym Euphorbia remyi A. Gray ex Boiss. var. kauaiensis O. Deg. & Sherff. As a perennial shrub, this hardy little plant typically develops multiple stems from near the ground and can grow up to 13-16 feet in height under the right conditions, though most specimens remain much smaller.
Where Does It Come From?
This plant is endemic to Hawaii, meaning it exists nowhere else on Earth naturally. More specifically, this variety is native to the island of Kauai, making it one of the island’s unique botanical treasures.

⚠️ Important Conservation Alert
Before you consider growing this plant, please read this carefully: Remy’s sandmat has a Global Conservation Status of S1T1 and is listed as Endangered in the United States. This means the plant is at extremely high risk of extinction in the wild.
If you’re interested in growing this species, it’s absolutely critical that you:
- Only obtain plants or seeds from verified, responsibly managed conservation sources
- Never collect from wild populations
- Consider participating in legitimate conservation efforts instead of private cultivation
- Contact local botanical gardens or conservation organizations for guidance
Growing Conditions and Care
Unfortunately, specific growing requirements for Remy’s sandmat are not well-documented in accessible sources, which is common for critically rare species. This lack of information underscores why conservation efforts typically focus on protecting existing wild populations rather than cultivation.
What we do know is that as a Hawaiian native, it likely thrives in tropical conditions similar to those found on Kauai. However, attempting to grow this plant without proper expertise and legitimate conservation purposes could inadvertently harm conservation efforts.
Supporting Conservation Instead
Rather than trying to grow this rare beauty in your garden, consider these meaningful alternatives:
- Support Hawaiian plant conservation organizations financially
- Grow other, less threatened Hawaiian native plants in your landscape
- Visit botanical gardens that participate in conservation programs
- Volunteer with habitat restoration projects if you live in Hawaii
The Bottom Line
Remy’s sandmat represents the incredible but fragile biodiversity of Hawaii. While the desire to grow rare and beautiful plants is understandable, sometimes the most loving thing we can do is admire from afar and support conservation efforts that work to ensure these botanical treasures survive for future generations.
If you’re passionate about Hawaiian native plants, focus on growing more common species that can benefit from cultivation while leaving the rarest ones to the experts working tirelessly to save them in their natural habitats.
