Hana Clermontia: A Rare Hawaiian Treasure for Your Native Garden
If you’re passionate about native Hawaiian plants and conservation gardening, the Hana clermontia (Clermontia samuelii hanaensis) might just capture your heart. This rare endemic shrub represents one of Hawaii’s most precious botanical treasures, though growing it comes with important responsibilities that every gardener should understand.
What Makes Hana Clermontia Special
The Hana clermontia belongs to the bellflower family and showcases the unique beauty of Hawaii’s native flora. As a perennial shrub, it typically grows as a multi-stemmed woody plant reaching 13 to 16 feet in height under ideal conditions. Like other members of the Clermontia genus, it likely produces stunning tubular flowers that evolved alongside Hawaii’s native birds.
You might also encounter this plant listed under its synonym, Clermontia hanaensis H. St. John, in older botanical references.

A Critical Conservation Concern
Important: Before you fall in love with the idea of growing Hana clermontia, you need to know that this plant has a Global Conservation Status of S1T1, meaning it’s critically imperiled. This rare status means that if you choose to grow this plant, you must only source it from reputable nurseries that use responsibly collected seeds or ethically propagated material. Never collect from wild populations.
Why Grow Hana Clermontia?
Despite the challenges, there are compelling reasons why dedicated native plant gardeners might want to include this species:
- Support conservation efforts by maintaining genetic diversity in cultivation
- Create authentic native Hawaiian landscapes
- Provide habitat for native Hawaiian birds and pollinators
- Participate in preserving Hawaii’s unique botanical heritage
Growing Conditions and Care
Hana clermontia thrives in USDA hardiness zones 10-11, making it suitable only for tropical and subtropical climates. In its native habitat, it grows in mesic to wet forest conditions, which gives us clues about its preferred growing environment:
- Light: Partial shade to filtered sunlight
- Moisture: Consistent moisture but well-draining soil
- Soil: Rich, organic forest-type soil
- Protection: Shelter from strong winds
- Humidity: High humidity levels
Landscape Design Ideas
If you’re fortunate enough to obtain this rare plant through responsible sources, it works beautifully in:
- Native Hawaiian plant collections
- Conservation gardens
- Shaded woodland gardens
- Educational botanical displays
Its shrub form makes it suitable as a specimen plant or as part of a mixed native planting, where it can provide structure and year-round interest.
The Bottom Line
Growing Hana clermontia is both a privilege and a responsibility. While its rarity makes it challenging to obtain and grow, successfully cultivating this species contributes to conservation efforts and helps preserve Hawaii’s irreplaceable botanical heritage. If you’re up for the challenge and can source plants responsibly, this rare beauty could become the crown jewel of your native Hawaiian garden.
Remember, the best way to help rare plants like Hana clermontia is to support conservation organizations, choose responsibly sourced plants, and never collect from wild populations. Every plant grown in cultivation is a small victory for conservation.
