Waihee Clermontia: A Possibly Lost Hawaiian Treasure

The Waihee clermontia (Clermontia multiflora) represents one of Hawaii’s most precious and possibly lost botanical treasures. This native Hawaiian shrub tells a sobering story about the fragility of island ecosystems and the urgent need for plant conservation.

A Plant on the Brink

Before we dive into the details of this remarkable plant, there’s something crucial you need to know: Clermontia multiflora has a Global Conservation Status of SH, meaning it’s Possibly Extirpated. In plain terms, this beautiful native Hawaiian shrub is known only from historical records, and there’s just a glimmer of hope that it might still exist somewhere in the wild.

This conservation status means that if you’re thinking about adding this plant to your garden, you’ll need to proceed with extreme caution and responsibility. Any specimens should only come from legitimate conservation programs or botanical institutions working to preserve Hawaiian native flora.

What Made This Plant Special

The Waihee clermontia was a perennial shrub that typically grew as a multi-stemmed woody plant, usually reaching heights of 13 to 16 feet (4 to 5 meters). Like other members of the bellflower family, it likely produced distinctive tubular flowers that were perfectly adapted to Hawaii’s native ecosystem.

Where It Called Home

This remarkable plant was endemic to Hawaii, meaning it existed nowhere else on Earth. It was part of the unique wet forest ecosystems that once covered much of the Hawaiian islands.

The Role It Would Have Played

In its natural habitat, Clermontia multiflora would have been an important part of Hawaii’s native plant community. Like other Clermontia species, it was likely pollinated by native Hawaiian birds, particularly the Hawaiian honeycreepers, creating intricate relationships that took thousands of years to develop.

Conservation and Responsible Gardening

Given its possibly extirpated status, here’s what you need to know if you’re interested in this plant:

  • Do not attempt to source this plant from wild collection
  • Only work with legitimate botanical institutions or conservation programs
  • Consider supporting Hawaiian native plant conservation efforts instead
  • Choose other native Hawaiian plants that are more readily available and less threatened

Better Alternatives for Your Hawaiian Native Garden

If you’re passionate about growing native Hawaiian plants, consider these alternatives that won’t contribute to the pressure on critically endangered species:

  • Other Clermontia species that are less threatened
  • Native Hawaiian shrubs like ʻōhiʻa lehua (Metrosideros polymorpha)
  • Indigenous ferns and other understory plants

A Call to Conservation

The story of Waihee clermontia serves as a powerful reminder of what we stand to lose when native ecosystems are threatened. While you might not be able to grow this particular plant in your garden, you can still make a difference by supporting native plant conservation, choosing other native species for your landscape, and spreading awareness about the importance of preserving our botanical heritage.

Sometimes the most responsible thing we can do as gardeners is to admire a plant from afar and work to protect what remains of its natural habitat. In the case of Clermontia multiflora, that might be our only hope of ensuring future generations have the chance to witness its beauty.
