This charming native shrub offers a unique opportunity to grow a piece of Hawaii’s natural heritage right in your garden – but there’s an important conservation story you need to know first.

What Makes This Plant Special?

The Kohala Summit melicope is a perennial shrub that’s as rare as it is beautiful. Endemic to Hawaii, this plant typically grows as a multi-stemmed woody shrub, usually staying under 13-16 feet tall. What makes it particularly appealing is its glossy green foliage and delicate clusters of small, cream-colored flowers that add a subtle elegance to any native plant collection.

A Plant with Many Names

Like many Hawaiian natives, this species has had quite the taxonomic journey. You might also see it listed under several historical names including Pelea pseudoanisata or Pelea cauliflora, but Melicope pseudoanisata is the current accepted botanical name.

Where It Calls Home

This melicope is found exclusively in Hawaii, where it naturally grows in the cool, misty cloud forests of higher elevations. It’s perfectly adapted to Hawaii’s unique island ecosystem and plays an important role in these specialized mountain habitats.

Conservation Alert: Handle with Care

Here’s where things get serious – the Kohala Summit melicope has a Global Conservation Status of S3, meaning it’s considered vulnerable. With only an estimated 21-100 occurrences and between 3,000-10,000 individuals remaining in the wild, this plant is genuinely rare. If you’re interested in growing this species, please only source plants from reputable native plant nurseries that use responsibly collected seeds or cuttings, never wild-collected plants.

Garden Role and Design Uses

In a Hawaiian native landscape, this melicope serves beautifully as an understory shrub. Its compact form and attractive foliage make it perfect for:

  • Native Hawaiian restoration gardens
  • Conservation-focused landscapes
  • Shaded woodland gardens
  • Areas where you want to showcase rare native plants

Growing Conditions and Care

The Kohala Summit melicope thrives in conditions that mimic its natural cloud forest habitat:

  • Climate: USDA hardiness zones 10-11 (tropical to subtropical)
  • Moisture: Consistent humidity and regular watering – this plant has a facultative wetland status, meaning it can handle both wet and moderately dry conditions
  • Light: Partial shade to filtered sunlight
  • Soil: Well-draining but moisture-retentive soil
  • Protection: Shelter from strong winds

Pollinator and Wildlife Benefits

While specific wildlife data for this species is limited, melicopes generally attract native Hawaiian insects with their small, fragrant flowers. By growing this plant, you’re supporting the intricate web of native Hawaiian pollinators and contributing to the preservation of endemic species relationships.

The Bottom Line

Should you plant the Kohala Summit melicope? If you’re committed to Hawaiian native plant conservation and can source the plant responsibly, absolutely! This rare shrub offers gardeners a chance to participate in preserving Hawaii’s unique botanical heritage. Just remember – with great rarity comes great responsibility. Always choose nursery-propagated plants and never collect from the wild.

For most gardeners, this plant represents more than just another addition to the landscape – it’s a living piece of conservation history and a commitment to protecting Hawaii’s irreplaceable native flora for future generations.
