Maui Flatsedge: A Critically Rare Hawaiian Native That Needs Our Help
Meet Maui flatsedge (Cyperus neokunthianus), a Hawaiian native sedge that’s facing a heartbreaking reality – it might already be gone from the wild. This unassuming grass-like perennial holds the sobering distinction of being one of Hawaii’s most critically endangered plants, with a conservation status that reads like a plea for help.
What Makes Maui Flatsedge Special?
Maui flatsedge belongs to the sedge family, making it a grass-like plant that once called the beautiful islands of Hawaii home. As a perennial, this plant was designed by nature to return year after year, but sadly, that natural cycle has been disrupted. You might also see this plant referenced by its scientific synonyms Cyperus kunthianus or Mariscus kunthianus in older botanical literature.
Where Did Maui Flatsedge Live?
This endemic Hawaiian species was native exclusively to Hawaii, with historical records pointing specifically to Maui. Being endemic means it evolved here and existed nowhere else on Earth – making its potential loss even more significant for Hawaii’s unique botanical heritage.

The Sobering Reality: A Plant on the Edge
Here’s where things get serious, fellow plant lovers. Maui flatsedge carries a Global Conservation Status of SH – which stands for Possibly Extirpated. In plain English, this means scientists know it existed historically, but there’s a real chance it might already be extinct in the wild. There’s still hope for rediscovery, but that hope grows dimmer with each passing year.
In the United States, this species is officially listed as Endangered, which is the most critical conservation status a plant can receive before being declared extinct.
Should You Try to Grow Maui Flatsedge?
This is where I need to be completely honest with you: you probably shouldn’t attempt to grow Maui flatsedge, and here’s why:
- The plant may already be extinct in the wild
- Any remaining specimens are of critical conservation value
- Growing conditions and care requirements are largely unknown
- Seeds or plants are not commercially available
- Cultivation should only be attempted by conservation professionals
How You Can Help Instead
While you can’t plant Maui flatsedge in your garden, you can still make a difference:
- Support Hawaiian native plant conservation organizations
- Choose other native Hawaiian sedges for your garden if you live in Hawaii
- Spread awareness about Hawaii’s endangered flora
- If you’re hiking in Hawaii and think you spot this plant, report it to local botanists immediately
The Bigger Picture
Maui flatsedge represents a sobering reminder of what we stand to lose when native habitats disappear. While we can’t turn back the clock on this particular species, we can learn from its story and work harder to protect the native plants that still have a fighting chance.
Every native plant we choose for our gardens, every invasive species we remove, and every dollar we donate to conservation efforts is a small victory in the larger battle to preserve our natural heritage. Sometimes the most important gardening lesson isn’t about what to plant – it’s about understanding what we might lose if we don’t act soon enough.
