Hinahina: A Silvery Hawaiian Treasure for Your Native Garden
Meet hinahina (Geranium cuneatum var. hololeucum), a charming native Hawaiian shrub that’s as beautiful as its melodic Hawaiian name. This silvery-leafed gem is a true island endemic, meaning it exists nowhere else on Earth except in the Hawaiian archipelago. If you’re looking to create an authentic Hawaiian landscape or simply want to grow something truly special, hinahina might just be the perfect addition to your garden.
What Makes Hinahina Special?
Hinahina is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall, though most garden specimens remain much more compact. What really sets this plant apart is its striking silvery-gray foliage that seems to shimmer in the Hawaiian sun, paired with delicate pink to white flowers that add a soft touch of color to the landscape.
This plant is scientifically known as Geranium cuneatum var. hololeucum, and you might also see it listed under its synonym Geranium cuneatum Hook. ssp. hololeucum. But honestly, hinahina rolls off the tongue much more beautifully!
Where Does Hinahina Call Home?
Hinahina is exclusively native to Hawaii, where it thrives on volcanic slopes and in dry forest areas across the islands. You won’t find this beauty growing wild anywhere else in the world, making it a true Hawaiian treasure.
Important Conservation Note
Before you fall head over heels for hinahina (and trust us, you will), there’s something important to know: this plant has a Global Conservation Status of S3T3, which indicates it faces some conservation challenges in its native habitat. This doesn’t mean you shouldn’t grow it—quite the opposite! Growing native plants like hinahina in appropriate settings can actually help support conservation efforts.
However, it does mean you should be extra careful about sourcing your plant responsibly. Always purchase hinahina from reputable native plant nurseries that propagate their plants ethically rather than collecting from wild populations.
Why Grow Hinahina in Your Garden?
There are plenty of reasons to welcome hinahina into your landscape:
- Authentic Hawaiian character: Perfect for creating genuine native Hawaiian landscapes

Perfect Garden Settings for Hinahina
Hinahina shines brightest in:
- Native Hawaiian plant gardens
- Xerophytic (drought-tolerant) landscapes
- Rock gardens and volcanic rock settings
- Slope stabilization projects
- Low-water Mediterranean-style gardens
Growing Hinahina Successfully
The good news is that hinahina isn’t particularly fussy once you understand its needs. This plant is adapted to USDA hardiness zones 10-11, so it’s best suited for tropical and subtropical climates.
Growing Conditions
- Light: Full sun to partial shade (morning sun with afternoon protection works well)
- Soil: Well-draining soil is absolutely essential—think volcanic, rocky, or sandy soils
- Water: Drought-tolerant once established, but appreciates occasional deep watering during dry spells
- Climate: Prefers warm, tropical conditions with good air circulation
Planting and Care Tips
- Plant in well-draining soil—poor drainage is hinahina’s biggest enemy
- Water regularly during the first growing season to help establish roots
- Once established, reduce watering frequency but water deeply when you do
- Light pruning can help maintain shape and encourage bushier growth
- Mulch around the base with volcanic rock or gravel rather than organic mulch
- Avoid over-fertilizing, as this plant is adapted to nutrient-poor soils
Supporting Hawaiian Ecosystems
By choosing to grow hinahina, you’re doing more than just adding a beautiful plant to your garden. You’re participating in the preservation of Hawaii’s unique botanical heritage and providing habitat for native pollinators and other wildlife. Plus, you’ll have the satisfaction of growing something truly special—a plant that exists nowhere else on our planet.
Remember, the key to success with hinahina is respecting its natural growing conditions: good drainage, appropriate climate, and most importantly, responsible sourcing.
