Pacific Cyrtandra: A Rare Hawaiian Native Worth Protecting in Your Garden
If you’re passionate about native Hawaiian plants and conservation gardening, you might want to learn about Pacific cyrtandra (Cyrtandra grayana). This perennial shrub represents one of Hawaii’s unique endemic species, though it comes with some important considerations for the responsible gardener.





What Is Pacific Cyrtandra?
Pacific cyrtandra is a native Hawaiian shrub belonging to the African violet family (Gesneriaceae). As a perennial, multi-stemmed woody plant, it typically grows as a shrub less than 13-16 feet in height, with several stems arising from or near the ground. Like many Hawaiian natives, this species has evolved specifically to thrive in the island’s unique ecosystem.
The plant is found exclusively in Hawaii, making it a true island endemic. Its natural distribution is limited to the Hawaiian islands, where it has adapted to local growing conditions over thousands of years.
Why Consider Pacific Cyrtandra for Your Garden?
There are compelling reasons to consider this native Hawaiian species, but also important cautions to keep in mind:
The Good News
- Native heritage: As a true Hawaiian endemic, it supports local ecosystem health
- Adaptability: Its facultative wetland status means it can grow in both wetland and non-wetland conditions
- Conservation value: Growing native species helps preserve Hawaii’s botanical heritage
- Unique character: Adds authentic Hawaiian flora to your landscape
Important Considerations
- Rarity status: With a Global Conservation Status of S2S3, this plant has some conservation concerns
- Limited availability: Rare plants are often difficult to source responsibly
- Specialized needs: As a Hawaiian endemic, it has specific growing requirements
Growing Pacific Cyrtandra Successfully
Given the limited cultivation information available for this specific species, growing Pacific cyrtandra requires some educated guesswork based on related species and its natural habitat preferences.
Climate Requirements
Pacific cyrtandra is naturally adapted to Hawaii’s tropical climate, which translates to USDA hardiness zones 10-12. If you’re gardening outside of Hawaii, you’ll likely need greenhouse conditions or indoor cultivation.
Growing Conditions
Based on its facultative wetland status and shrub habit, Pacific cyrtandra likely prefers:
- Partial shade to filtered sunlight
- Consistently moist but well-draining soil
- High humidity levels
- Protection from strong winds
Garden Placement
This shrub works well in:
- Native Hawaiian landscape designs
- Shade gardens and understory plantings
- Conservation-focused gardens
- Areas that can accommodate flexible moisture levels
Responsible Sourcing Is Critical
Here’s the most important part: if you’re interested in growing Pacific cyrtandra, you must ensure you’re obtaining plants from responsible, legal sources. Given its S2S3 conservation status, wild collection could harm remaining populations. Look for:
- Reputable native plant nurseries in Hawaii
- Conservation organizations with propagation programs
- Botanical gardens that may offer seeds or plants
- Academic institutions involved in Hawaiian plant conservation
The Bottom Line
Pacific cyrtandra represents the kind of plant that makes native gardening both exciting and challenging. While its rarity means you should approach cultivation thoughtfully and responsibly, growing this species can contribute to conservation efforts while adding authentic Hawaiian character to your garden.
If you’re gardening in Hawaii and can source this plant responsibly, it’s worth considering for a native landscape. However, if you’re new to native Hawaiian plants, you might want to start with more common native species before tackling rare ones like Pacific cyrtandra.
Remember: the goal isn’t just to grow rare plants, but to grow them in ways that support rather than threaten their survival in the wild. Pacific cyrtandra deserves that level of respect and care.
