Oahu Wild Coffee: A Rare Hawaiian Native Worth Protecting
If you’re passionate about Hawaiian native plants and conservation gardening, you’ve likely heard whispers about the elusive Oahu wild coffee. This remarkable shrub, scientifically known as Psychotria hexandra oahuensis var. rockii, represents one of Hawaii’s botanical treasures that’s becoming increasingly difficult to find in the wild.
What Makes Oahu Wild Coffee Special?
Oahu wild coffee belongs to the coffee family (Rubiaceae), though don’t expect your morning brew from this beauty! This perennial shrub is a true Hawaiian endemic, meaning it exists naturally nowhere else on Earth. Like most shrubs, it’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, making it a manageable size for many landscape applications.
You might also see this plant referenced by its scientific synonym, Psychotria hexandra H. Mann var. st.-johnii Fosberg, in older botanical literature.
Where Does It Grow?
As its common name suggests, this native beauty calls Hawaii home, specifically the island of Oahu. It’s part of Hawaii’s unique flora that evolved in isolation over millions of years, developing characteristics found nowhere else on the planet.

The Conservation Reality Check
Here’s where we need to have a serious conversation. Oahu wild coffee carries a Global Conservation Status of S2TH, indicating it’s quite rare and potentially at risk. This means that while we absolutely should celebrate and grow native Hawaiian plants, we need to be extra thoughtful about how we source this particular species.
Important: If you’re interested in growing Oahu wild coffee, only obtain plants from reputable native plant nurseries or conservation organizations that can verify responsible sourcing. Never collect plants from the wild – this could harm already vulnerable populations.
Why Consider Growing Oahu Wild Coffee?
Despite the sourcing challenges, there are compelling reasons to include this plant in appropriate Hawaiian landscapes:
- Supports native Hawaiian biodiversity
- Connects your garden to Hawaii’s natural heritage
- Contributes to conservation efforts when responsibly grown
- Provides authentic native character to island landscapes
Growing Conditions and Care
Unfortunately, specific growing information for this rare variety is limited in horticultural literature. However, based on its native Hawaiian origins and shrub growth habit, it likely prefers:
- Warm, tropical conditions year-round
- Well-draining soil
- Partial shade to filtered sunlight
- Regular moisture without waterlogging
If you’re fortunate enough to obtain responsibly sourced plants, work with local Hawaiian native plant specialists who can provide specific guidance for your particular microclimate and soil conditions.
The Bottom Line
Oahu wild coffee represents both the incredible beauty and fragility of Hawaii’s native plant communities. While it’s not a plant for every gardener due to its rarity and specific needs, those committed to Hawaiian native plant conservation and blessed with appropriate growing conditions might find it a worthy addition to their landscape.
Remember: the best way to support rare native plants like Oahu wild coffee is through responsible cultivation, habitat protection, and supporting organizations working to preserve Hawaii’s unique botanical heritage. Sometimes the most meaningful way to appreciate a rare plant is simply knowing it exists and supporting its conservation from afar.
