Kolekole Cyanea: A Rare Hawaiian Treasure Worth Protecting
If you’re passionate about native Hawaiian plants, you’ve probably heard whispers about the kolekole cyanea (Cyanea kolekoleensis) – and for good reason. This extraordinary shrub represents one of Hawaii’s most precious botanical gems, though sadly, it’s also one of its most endangered.
What Makes Kolekole Cyanea Special
The kolekole cyanea belongs to the bellflower family and showcases the unique beauty that makes Hawaiian flora so captivating. As a perennial shrub, it typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall. What sets this plant apart isn’t just its rarity – it’s a living piece of Hawaii’s natural heritage that has evolved nowhere else on Earth.
You might also see this plant referred to by its scientific synonym, Delissea kolekoleensis, in older botanical references.
Where Does It Come From
This remarkable shrub is endemic to Hawaii, meaning it exists naturally nowhere else in the world. Within Hawaii, its distribution is extremely limited, making every single plant incredibly precious to the islands’ ecosystem.

A Critical Conservation Concern
Here’s what every gardener needs to know: The kolekole cyanea carries a Global Conservation Status of S1, which translates to Critically Imperiled. In plain terms, this means there are typically five or fewer occurrences of this plant in the wild, with fewer than 1,000 individual plants remaining. It’s also listed as Endangered in the United States.
If you’re considering adding this plant to your garden, please – and we cannot stress this enough – only source it from reputable native plant nurseries that propagate from legally obtained, responsibly sourced material. Never collect from wild populations.
Growing Conditions and Care
Should you be fortunate enough to obtain responsibly sourced kolekole cyanea, here’s what you need to know about keeping it happy:
- Climate: Thrives in USDA hardiness zones 10-12 (tropical conditions only)
- Moisture: Prefers consistent moisture but not waterlogged conditions – it’s classified as Facultative Upland, meaning it usually grows in non-wetland areas but can tolerate some wetness
- Light: Likely prefers partial shade, mimicking its natural forest habitat
- Soil: Well-draining soil is essential to prevent root rot
Garden Role and Landscape Use
The kolekole cyanea isn’t your typical landscape plant. Its primary value lies in conservation gardens, specialized native Hawaiian plant collections, and educational displays. If you’re creating a native Hawaiian garden or participating in conservation efforts, this shrub can serve as a stunning focal point while contributing to species preservation.
This plant is best suited for:
- Conservation gardens
- Native Hawaiian plant collections
- Educational botanical displays
- Specialized tropical gardens focused on rare species
Supporting Hawaiian Wildlife
As a native Hawaiian species, the kolekole cyanea likely plays important roles in supporting local wildlife, particularly native birds and insects that have co-evolved with Hawaiian flora. By growing this plant responsibly, you’re not just adding beauty to your garden – you’re participating in conservation efforts that support entire ecosystems.
The Bottom Line
The kolekole cyanea represents both an incredible opportunity and a serious responsibility. While its rarity makes it a challenging plant to obtain and grow, those who do so ethically become partners in conservation. If you’re not ready for the commitment that comes with growing an endangered species, consider supporting conservation organizations working to protect Hawaiian native plants instead.
Remember: every kolekole cyanea in cultivation represents hope for this species’ future. With careful, responsible growing practices, we can help ensure that future generations will have the chance to appreciate this remarkable Hawaiian treasure.
