Koloa Clermontia: A Hawaiian Native Worth Growing
If you’re looking to add authentic Hawaiian beauty to your garden while supporting native wildlife, meet the Koloa clermontia (Clermontia carinifera). This enchanting native shrub brings a touch of the islands’ natural heritage right to your backyard, complete with stunning tubular flowers that’ll make your neighbors do a double-take.
What Makes Koloa Clermontia Special?
The Koloa clermontia is a true Hawaiian original – a perennial shrub that’s been calling the islands home long before any of us arrived. As a member of the bellflower family, this multi-stemmed beauty typically grows to about 13-16 feet tall, though it can stay more compact depending on growing conditions. What really sets it apart are those gorgeous curved, tubular flowers in shades of purple and violet-blue that seem to dance in the island breeze.
Where Does It Come From?
This native gem is endemic to the Hawaiian Islands, naturally occurring on Kauai, Oahu, Molokai, and Maui. You’ll find it thriving in the understory of native forests, where it has evolved alongside other indigenous plants and animals for thousands of years.
Why You’ll Love Growing Koloa Clermontia
Beyond its obvious beauty, there are plenty of reasons to welcome this native into your garden:
- It’s perfectly adapted to Hawaiian growing conditions
- The unique flowers add exotic appeal to any landscape
- You’re supporting native Hawaiian ecosystems
- It provides important habitat for native birds
- Low maintenance once established
- Great for shade gardens where other plants might struggle
Supporting Native Wildlife
Here’s where it gets really cool – those distinctively shaped flowers aren’t just pretty to look at. They’ve evolved specifically to attract Hawaiian honeycreepers, native birds that serve as the plant’s primary pollinators. By growing Koloa clermontia, you’re helping support these endangered bird species and maintaining important ecological relationships.
Growing Conditions and Care
The good news? Koloa clermontia isn’t particularly fussy once you understand its preferences. Here’s what it needs to thrive:
- Light: Partial to full shade (mimics its natural forest habitat)

- Water: Consistent moisture without waterlogging
- Climate: USDA zones 10-12 (tropical and subtropical areas)
- Protection: Shelter from strong winds
Planting and Care Tips
Getting your Koloa clermontia off to a good start is pretty straightforward:
- Choose a spot with morning sun and afternoon shade
- Prepare the soil with plenty of compost or leaf mold
- Water regularly, especially during dry periods
- Apply a thick layer of organic mulch to retain moisture
- Protect from strong trade winds with taller plants or structures
- Be patient – like many natives, it may take time to establish
Perfect Garden Companions
Koloa clermontia plays well with other Hawaiian natives. Consider pairing it with native ferns, ohia trees, or other indigenous understory plants to create an authentic Hawaiian forest garden experience.
The Bottom Line
If you live in Hawaii or another tropical zone, Koloa clermontia deserves serious consideration for your landscape. It’s not just another pretty plant – it’s a living piece of Hawaiian natural history that supports native wildlife while adding unique beauty to your garden.
