Honolulu Melicope: A Rare Hawaiian Native Worth Protecting in Your Garden
If you’re passionate about Hawaiian native plants and conservation gardening, the Honolulu melicope (Melicope hosakae) might just capture your heart. This charming endemic shrub brings a piece of authentic Hawaiian flora to your landscape, but there’s something important you need to know before adding it to your wishlist.
What Makes Honolulu Melicope Special
The Honolulu melicope is a perennial shrub that typically grows as a multi-stemmed woody plant, usually reaching less than 13-16 feet in height. What makes this plant truly special is its exclusive Hawaiian heritage – it’s found nowhere else on Earth except the island of Oahu, specifically in the Honolulu area.
You might also see this plant listed under its botanical synonyms, including Melicope honoluluensis, Pelea honoluluensis, or Pelea hosakae, but they’re all the same remarkable species.
Native Range and Current Status
This endemic Hawaiian treasure calls only the state of Hawaii home, making it incredibly special but also vulnerable. The Honolulu melicope has a Global Conservation Status of S2S3, which means it’s uncommon to rare in its natural habitat.
Important Rarity Considerations
Here’s what every gardener needs to know: Because the Honolulu melicope is rare, it’s crucial to source plants only from reputable native plant nurseries that propagate from ethically collected seeds or cuttings. Never collect from wild populations, and always verify that any plants you purchase come from responsible propagation programs.
Garden Appeal and Landscape Role
When grown successfully, the Honolulu melicope offers subtle but distinctive beauty with its glossy green foliage and clusters of small, cream-colored flowers. As an understory shrub, it plays a perfect supporting role in native Hawaiian landscapes, thriving in the dappled light beneath taller native trees.
This shrub works beautifully in:
- Native Hawaiian restoration gardens
- Tropical conservation landscapes
- Understory plantings in shade gardens
- Educational or botanical garden displays
Growing Conditions and Care
The Honolulu melicope is suited for USDA hardiness zones 10-11, thriving in tropical conditions. Here’s what this Hawaiian native prefers:

- Water: Moderate moisture – avoid both drought stress and waterlogged conditions
- Protection: Shield from strong winds, which can damage its delicate structure
Planting and Care Tips
Successfully growing this rare native requires some attention to detail:
- Apply organic mulch around the base to retain moisture and suppress weeds

- Plant in a location protected from harsh afternoon sun and strong trade winds
- Consider companion planting with other native Hawaiian species for a more authentic ecosystem approach
