Molokai Islandmint: A Rare Hawaiian Treasure We May Have Lost

Meet Molokai islandmint (Haplostachys bryanii), one of Hawaii’s most elusive native plants. This unassuming member of the mint family might not look like much, but it holds a special place in Hawaiian botanical history – and unfortunately, it’s a place we’re desperately trying to preserve.

What Makes This Plant Special?

Molokai islandmint is what botanists call a forb – essentially a soft-stemmed perennial herb without woody growth. As part of the mint family, it likely once graced the Hawaiian landscape with its subtle beauty, though it was never the showiest plant in the garden.

This little plant is endemic to Hawaii, meaning it evolved here and exists nowhere else on Earth. More specifically, it’s native to the island of Molokai, which gives it both its common name and its unique character.

The Conservation Reality Check

Here’s where things get serious: Molokai islandmint has a Global Conservation Status of SH, which stands for Possibly Extirpated. In plain English? This plant is known only from historical records, and scientists aren’t sure if it still exists in the wild. There’s still hope for rediscovery, but that hope is growing thinner with each passing year.

Should You Plant Molokai Islandmint?

The short answer is: probably not, and here’s why. With such a precarious conservation status, any remaining genetic material of this species is incredibly precious. Unless you’re working with a legitimate conservation program or botanical institution, it’s best to admire this plant from afar and support conservation efforts instead.

If you do have access to responsibly sourced material through official conservation channels, here’s what little we know about growing it:

  • It’s adapted to tropical Hawaiian conditions (USDA zones 10-12)
  • As a native Hawaiian plant, it likely prefers well-draining soils
  • Being a mint family member, it may attract native Hawaiian pollinators
  • Specific growing requirements remain largely unknown

Better Alternatives for Your Hawaiian Garden

Instead of trying to grow this rare species, consider these more readily available Hawaiian native mints and herbs:

  • Other Haplostachys species that are more stable
  • Native Hawaiian herbs that support local ecosystems
  • Well-established native plants that won’t put rare species at risk

How You Can Help

The best way to support Molokai islandmint isn’t by growing it – it’s by supporting Hawaiian plant conservation efforts. Consider:

  • Donating to Hawaiian botanical gardens and conservation programs
  • Volunteering for native plant restoration projects
  • Choosing other native Hawaiian plants for your garden
  • Spreading awareness about Hawaii’s endangered flora

Sometimes the most responsible thing we can do as gardeners is to step back and let the experts handle the rarest treasures. Molokai islandmint may be too precious for our home gardens, but that doesn’t make it any less worthy of our respect and protection.

Haplostachys bryanii is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Haplostachys bryanii is also known as:

Haplostachys bryanii Sherff var. microdonta | USDA symbol: HABRM
Haplostachys bryanii Sherff var. robusta | USDA symbol: HABRR

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
