Mt. Kaala Melicope: A Rare Hawaiian Native Worth Protecting in Your Garden
If you’re passionate about Hawaiian native plants and conservation gardening, the Mt. Kaala melicope (Melicope sandwicensis) might just capture your heart. This charming endemic shrub brings a piece of Hawaii’s mountainous wilderness right to your garden, though its rarity makes it a plant that deserves special consideration and respect.
What Makes Mt. Kaala Melicope Special?
The Mt. Kaala melicope is a perennial shrub that typically grows as a multi-stemmed woody plant, usually reaching heights of less than 13-16 feet. What makes this plant particularly special is its status as a true Hawaiian endemic—it grows naturally nowhere else on Earth except in Hawaii. You might also encounter this plant listed under its botanical synonyms, including Pelea sandwicensis or Melicope cinereops, but they all refer to the same remarkable species.
Where Does It Come From?
This native beauty calls Hawaii home, with populations found primarily on Oahu’s Mt. Kaala and other high-elevation areas throughout the Hawaiian Islands. It’s perfectly adapted to Hawaii’s unique climate and ecosystem, having evolved in isolation over thousands of years.
A Word of Caution: This Plant is Rare
Before you rush out to find one for your garden, there’s something important you need to know. The Mt. Kaala melicope has a Global Conservation Status of S2, meaning it’s considered Imperiled. This classification indicates extreme rarity, with typically only 6 to 20 occurrences remaining in the wild and fewer than 1,000 to 3,000 individual plants total. This makes it especially vulnerable to extinction.
If you’re interested in growing this plant, please only source it from reputable native plant nurseries that propagate it responsibly, never from wild collection. By choosing responsibly sourced plants, you’re supporting conservation efforts rather than contributing to the species’ decline.
Why Grow Mt. Kaala Melicope?
Despite—or perhaps because of—its rarity, there are compelling reasons to consider this plant for your Hawaiian native garden:
- Conservation impact: Growing responsibly sourced specimens helps preserve genetic diversity and supports conservation efforts
- Authentic Hawaiian character: Adds genuine native appeal to restoration projects and native gardens

Growing Conditions and Care
Mt. Kaala melicope thrives in conditions similar to its native mountain habitat. Here’s what you need to know:
Climate Requirements: Best suited for USDA hardiness zones 10-12, which matches Hawaii’s tropical and subtropical conditions.
Light and Location: Prefers partial shade to full sun conditions. It works beautifully as an understory plant in woodland gardens or as part of a native Hawaiian landscape design.

Planting and Care Tips
- Plant in well-draining soil with good organic matter
- Apply mulch around the base to retain moisture and regulate soil temperature
- Provide some protection from strong winds, especially when young
