Waianae Range Labordia: A Critically Endangered Hawaiian Native Worth Protecting

If you’re passionate about native Hawaiian plants and conservation, the Waianae Range labordia might just capture your heart—though growing this rare beauty comes with significant responsibility. This critically endangered shrub represents one of Hawaii’s most precious botanical treasures, teetering on the edge of extinction with fewer than 1,000 individuals remaining in the wild.

What Makes This Plant Special

The Waianae Range labordia (Labordia kaalae) is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall. What sets this plant apart isn’t just its rarity—it’s also quite lovely, producing small white tubular flowers that contrast beautifully against its glossy green foliage. The compact growth habit makes it an attractive specimen for those lucky enough to grow it.

Where It Calls Home

This endemic Hawaiian species is found exclusively in the Waianae Mountains on the island of Oahu. Its entire natural range is incredibly restricted, which contributes to its critically imperiled status. The plant has adapted to the specific conditions of these volcanic slopes, making it a true island endemic.

A Word of Caution: Rarity Matters

Here’s the crucial part every gardener needs to know: Labordia kaalae has a Global Conservation Status of S1, meaning it’s critically imperiled. With typically 5 or fewer occurrences and very few remaining individuals in the wild, this plant is hanging by a thread. If you’re considering growing this species, you absolutely must ensure any plant material comes from responsible, legal sources—never from wild collection.

Growing Conditions and Care

Successfully growing Waianae Range labordia requires dedication and the right conditions:

  • Climate: USDA hardiness zones 10-11 (tropical conditions only)
  • Soil: Well-draining volcanic or similar soils
  • Light: Partial shade preferred
  • Moisture: Consistent humidity and careful watering
  • Protection: Shelter from strong winds

This isn’t a plant for beginners—it requires specialized care and understanding of native Hawaiian growing conditions.

Benefits for Your Garden and Wildlife

When grown successfully, Waianae Range labordia offers unique benefits:

  • Attracts native Hawaiian moths and other pollinators with its tubular flowers
  • Serves as a conversation starter about Hawaiian conservation
  • Contributes to ex-situ conservation efforts
  • Provides authentic native character to Hawaiian landscape designs

Is This Plant Right for You?

Honestly? Most gardeners should probably admire this plant from afar. Growing Waianae Range labordia is more about conservation than casual gardening. Consider this plant only if you:

  • Live in Hawaii or have access to appropriate tropical growing conditions
  • Are committed to conservation and have experience with rare plants
  • Can source plants through legitimate conservation programs
  • Understand the responsibility of growing critically endangered species

The Bottom Line

Waianae Range labordia represents both the beauty and fragility of Hawaii’s native flora. While it’s a stunning addition to native Hawaiian gardens, growing it comes with the serious responsibility of conservation stewardship. If you’re not ready for that commitment, consider supporting conservation organizations working to protect this species in the wild instead. Sometimes the best way to help a rare plant is to ensure its natural habitat remains intact.

For most gardeners interested in native Hawaiian plants, there are other beautiful and less critically endangered options that can provide similar aesthetic appeal without the conservation concerns. But for those truly committed to preserving Hawaii’s botanical heritage, this little shrub offers a meaningful way to contribute to conservation efforts—one garden at a time.
