Eleele Cyanea: A Critically Rare Hawaiian Native Worth Protecting
If you’re passionate about native Hawaiian plants and conservation gardening, you may have heard whispers about the eleele cyanea (Cyanea eleeleensis). This remarkable native Hawaiian shrub represents both the beauty and fragility of Hawaii’s unique flora—and sadly, it’s teetering on the edge of extinction.
What Makes Eleele Cyanea Special?
The eleele cyanea belongs to the bellflower family and showcases the distinctive beauty that makes Hawaiian lobelias so captivating. As a perennial shrub, it typically grows as a multi-stemmed woody plant reaching heights of 13 to 16 feet, though it can sometimes develop into a single-stemmed specimen under the right conditions.
Also known by its scientific synonym Delissea eleeleensis, this plant is exclusively native to Hawaii, where it once thrived in the islands’ unique ecosystems.
Geographic Distribution and Current Status
Historically, eleele cyanea was found in Hawaii, but here’s where the story takes a sobering turn. This species currently holds a Global Conservation Status of SH—meaning it’s possibly extirpated, known only from historical records. In the United States, it’s classified as Endangered, with researchers still holding onto hope for rediscovery in the wild.

The Reality of Growing Eleele Cyanea
Important Conservation Notice: Given its critically endangered status, we strongly recommend that if you’re considering growing eleele cyanea, you only do so with responsibly sourced material from legitimate conservation programs or botanical institutions.
This isn’t your typical garden center find—and for good reason. The rarity of this species means that any cultivation efforts should support conservation goals rather than casual gardening.
Growing Conditions and Care
If you’re working with a conservation organization or botanical garden, eleele cyanea requires very specific conditions:
- Climate: Tropical conditions (USDA zones 10-12)
- Habitat: Prefers facultative upland conditions—it usually grows in non-wetland areas but can tolerate some moisture
- Environment: Needs the humid, stable conditions of Hawaiian forests
- Space: Allow room for its potential 13-16 foot height and multi-stemmed growth
Role in Conservation Gardens
In the right setting, eleele cyanea serves as more than just a plant—it’s a living piece of Hawaiian heritage. It’s best suited for:
- Specialized native Hawaiian plant collections
- Botanical gardens with conservation missions
- Educational landscapes focused on endangered species
- Research facilities working on Hawaiian plant conservation
Supporting Hawaiian Native Plants
While most home gardeners won’t be able to grow eleele cyanea, you can still support Hawaiian native plant conservation by:
- Growing other native Hawaiian species that are more readily available
- Supporting botanical gardens and conservation organizations
- Learning about and advocating for endangered plant protection
- Choosing native plants over invasive species in your landscape
The Bigger Picture
The story of eleele cyanea reminds us why native plant conservation matters. Every species lost represents not just a plant, but an entire web of relationships—with pollinators, wildlife, and the broader ecosystem. While this particular species may be incredibly rare, its story highlights the importance of protecting the native plants we still have.
If you’re drawn to Hawaiian native plants, consider this a call to action: support conservation efforts, grow the native species that are available, and help ensure that future generations might once again see eleele cyanea thriving in Hawaiian forests.
