Windyridge Cyrtandra: A Rare Hawaiian Treasure for Your Shade Garden
If you’re looking to add a touch of authentic Hawaiian beauty to your tropical garden while supporting conservation efforts, the windyridge cyrtandra (Cyrtandra sessilis) might just be the perfect plant for you. This remarkable native Hawaiian shrub is more than just a pretty face – it’s a living piece of Hawaii’s natural heritage that desperately needs our help to survive.
What Makes Windyridge Cyrtandra Special?
Windyridge cyrtandra is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet in height. Like many Hawaiian natives, this beauty has evolved specifically for the unique conditions of the islands, making it a true endemic treasure found nowhere else on Earth.
This lovely shrub produces small, tubular flowers that have co-evolved with Hawaii’s native pollinators, including native birds and insects. Its attractive foliage and delicate blooms make it an excellent choice for adding authentic island character to shaded garden areas.
Where Does It Naturally Grow?
Cyrtandra sessilis is found exclusively in Hawaii, where it grows naturally in moist forest environments. The plant thrives in the understory of native Hawaiian forests, preferring the dappled light and consistent moisture these habitats provide.
A Plant in Crisis: Understanding Its Endangered Status
Important Conservation Note: Before you fall in love with this plant (and you will!), there’s something crucial you need to know. Windyridge cyrtandra has a Global Conservation Status of S1, meaning it’s critically imperiled. In the United States, it’s classified as Endangered, with typically five or fewer occurrences and very few remaining individuals in the wild.
This means if you choose to grow this plant, you must source it responsibly from reputable native plant nurseries or conservation programs – never collect from wild populations.
Perfect Growing Conditions
Windyridge cyrtandra is naturally a facultative upland plant, meaning it usually grows in non-wetland areas but can tolerate some moisture. Here’s what this Hawaiian beauty needs to thrive:
- Light: Partial to full shade (mimicking its natural forest understory habitat)
- Soil: Moist, well-draining, organic-rich soil
- Water: Consistent moisture without waterlogging
- Climate: USDA hardiness zones 10-12 only (tropical conditions)
- Humidity: High humidity levels preferred
Garden Design and Landscaping Uses
This charming shrub works beautifully in several garden settings:
- Native Hawaiian gardens: Perfect for authentic island landscaping
- Shade gardens: Excellent understory plant for tropical shade areas
- Conservation gardens: Ideal for gardeners interested in preserving rare species
- Rain gardens: Can handle occasional moisture fluctuations
Planting and Care Tips
Growing windyridge cyrtandra successfully requires attention to its native habitat preferences:
- Plant in a location with morning sun and afternoon shade
- Ensure excellent drainage while maintaining consistent soil moisture
- Add plenty of organic matter to the soil before planting
- Mulch around the base to retain moisture and suppress weeds
- Water regularly during dry periods, but avoid overwatering

Supporting Pollinators and Wildlife
By growing windyridge cyrtandra, you’re not just adding beauty to your garden – you’re creating habitat for Hawaii’s native pollinators. The plant’s tubular flowers are specifically adapted to attract native Hawaiian birds and insects, making your garden a valuable refuge for these important species.
