Cliffside Cyrtandra: Hawaii’s Endangered Forest Jewel
Meet the cliffside cyrtandra (Cyrtandra paliku), one of Hawaii’s most precious and precarious native plants. This remarkable shrub represents both the incredible diversity of Hawaiian flora and the urgent need for plant conservation in our island ecosystems.
A Rare Hawaiian Native
Cyrtandra paliku is exclusively native to Hawaii, where it grows naturally in the state’s lush wet forests. As a member of the African violet family, this perennial shrub has adapted to thrive in Hawaii’s unique tropical environment over thousands of years of evolution.
This species is found only in Hawaii, making it a true endemic treasure of the islands.

Why This Plant Needs Our Attention
Critical Conservation Status: Before we dive into growing information, it’s essential to understand that cliffside cyrtandra is critically endangered. With a Global Conservation Status of S1 (Critically Imperiled) and federal Endangered Species protection, this plant is hanging by a thread in the wild. Typically, this status means there are only five or fewer known populations and fewer than 1,000 individual plants remaining.
Physical Characteristics and Growth Habits
As a shrub, cliffside cyrtandra is a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it may grow differently depending on its specific environment. Like other members of its genus, it likely produces tubular flowers that are adapted for pollination by Hawaii’s native birds and insects.
The plant is a perennial, meaning it lives for multiple years and doesn’t need to be replanted annually. Its growth habit makes it well-suited for the understory of Hawaii’s native forests.
Natural Habitat and Growing Conditions
In its natural habitat, cliffside cyrtandra thrives in:
- Consistently moist, well-draining forest soils
- Shaded understory conditions
- High humidity environments
- Areas with regular rainfall or moisture
The plant has a wetland status of Facultative Wetland in Hawaii, meaning it usually grows in wetland areas but can occasionally be found in drier locations.
Can You Grow Cliffside Cyrtandra?
The Conservation Reality: While we’d love to encourage everyone to grow native plants, cliffside cyrtandra presents a unique situation. Due to its critically endangered status, this plant should only be cultivated through official conservation programs or with properly sourced, legally obtained plant material.
If you’re interested in supporting this species:
- Contact local Hawaiian botanical gardens or conservation organizations
- Support habitat restoration efforts in Hawaii
- Consider growing other native Hawaiian Cyrtandra species that are less threatened
- Participate in citizen science projects that monitor rare plant populations
Climate Requirements
Cliffside cyrtandra requires tropical conditions similar to its native Hawaiian habitat, limiting cultivation to USDA hardiness zones 11-12. This means it can only survive year-round in the warmest parts of Hawaii, southern Florida, and similar tropical climates.
Supporting Hawaiian Plant Conservation
Instead of attempting to grow this rare species in your garden, consider these alternatives that support Hawaiian conservation:
- Plant other native Hawaiian species that are more readily available
- Support organizations working to protect Hawaiian forest habitats
- Learn about and share information about Hawaii’s unique endemic flora
- Visit botanical gardens that maintain conservation collections of rare Hawaiian plants
The Bigger Picture
Cliffside cyrtandra serves as a reminder of how precious and fragile our native plant communities can be. While this particular species may not be suitable for typical home gardens due to its endangered status, it highlights the importance of choosing native plants for our landscapes and supporting conservation efforts.
By understanding and respecting the conservation needs of species like cliffside cyrtandra, we become better stewards of our natural heritage and help ensure that future generations can appreciate these remarkable plants in their native habitats.
