A Plant That Needs Our Help
Here’s something important to know: pua’akuhinia has a Global Conservation Status of S3, which means it’s considered vulnerable. With typically only 21 to 100 occurrences or between 3,000 and 10,000 individuals in the wild, this plant is facing challenges in its natural habitat. This makes growing it in gardens even more meaningful – you’re essentially becoming a conservation partner!
Important note: If you decide to grow pua’akuhinia, please only purchase from reputable native plant nurseries that use responsibly sourced, nursery-propagated material. Never collect plants from the wild.
What’s It Like in the Garden?
Pua’akuhinia brings a unique architectural presence to any landscape. Its rosette of sword-like leaves creates dramatic focal points and adds texture that’s distinctly tropical yet sophisticated. The silvery-green foliage catches light beautifully and provides year-round interest as a perennial.
This plant works wonderfully in:
- Native Hawaiian plant gardens
- Bog or moisture-loving plant collections
- Areas where you want a striking architectural accent
- Conservation-focused landscapes
Growing Conditions
Pua’akuhinia has some specific preferences that reflect its natural habitat. It’s classified as a facultative wetland plant, which means it usually occurs in wetlands but can adapt to non-wetland conditions too. This gives you some flexibility in placement, but it generally prefers:
- Consistently moist to wet soils
- Well-draining but moisture-retentive growing medium
- Partial shade to full sun exposure
- Cool temperatures when possible
- USDA hardiness zones 10-11
Planting and Care Tips
Success with pua’akuhinia comes down to understanding its moisture-loving nature:
- Soil: Use a well-draining potting mix that retains moisture well
- Watering: Keep soil consistently moist but not waterlogged
- Location: Choose a spot with morning sun and afternoon shade if possible
- Mulching: Apply organic mulch to help retain moisture
- Fertilizing: Use a balanced, slow-release fertilizer sparingly

- Want to grow authentic Hawaiian native plants
- Enjoy unique, architectural plant forms
