Green-Flower Clermontia: A Rare Hawaiian Treasure on the Brink
Meet the green-flower clermontia (Clermontia peleana singuliflora), a Hawaiian native shrub that represents both the incredible diversity of Hawaii’s native flora and the fragility of island ecosystems. This unique plant tells a sobering story about conservation and the importance of protecting our rarest native species.
A Plant with Many Names
Botanically known as Clermontia peleana singuliflora, this shrub has gone by several scientific names throughout its taxonomic history, including Clermontia clermontioides var. barbata and Clermontia singuliflora. These name changes reflect ongoing research into the complex relationships within the Clermontia genus, a group of plants found nowhere else in the world except Hawaii.
Where It Once Called Home
The green-flower clermontia was endemic to Hawaii, meaning it evolved there and existed nowhere else on Earth. This remarkable shrub once grew in the montane wet forests of the Hawaiian islands, thriving in the cool, misty conditions found at higher elevations.

A Conservation Crisis
Important Conservation Alert: Clermontia peleana singuliflora carries a Global Conservation Status of SH, which means it is Possibly Extirpated. This sobering designation indicates that the plant is known only from historical records, with no confirmed sightings in recent years, though there remains some hope for rediscovery.
What Made It Special
As a perennial shrub, the green-flower clermontia would have been a multi-stemmed woody plant, typically growing less than 13-16 feet tall. Like other members of the Clermontia family, it likely produced distinctive tubular flowers that were perfectly adapted for pollination by Hawaii’s native birds, particularly the Hawaiian honeycreepers that co-evolved with these plants over millions of years.
Should You Try to Grow It?
Given its possibly extirpated status, we strongly recommend against attempting to cultivate this plant unless you’re working with a legitimate conservation organization that has responsibly sourced genetic material. Even then, cultivation should only be undertaken as part of formal conservation efforts.
Instead, consider supporting conservation efforts for Hawaii’s native plants and choosing other native Hawaiian species that are more readily available and less threatened for your garden.
Better Native Alternatives
If you’re interested in native Hawaiian plants, consider these alternatives that can help support local ecosystems without putting rare species at risk:
- Other Clermontia species that are less threatened
- Native Hawaiian shrubs from conservation nurseries
- Plants that support native Hawaiian birds and pollinators
How You Can Help
While you might not be able to grow the green-flower clermontia in your garden, you can still make a difference:
- Support Hawaiian native plant conservation organizations
- Choose native plants for your landscape when possible
- Learn about and share the stories of rare and endangered plants
- Advocate for habitat protection and restoration
The story of Clermontia peleana singuliflora serves as a poignant reminder of what we stand to lose when native habitats disappear. While we may not be able to bring this particular plant back from the brink, we can work to prevent other species from following the same path toward extinction.
