‘Akoko: A Critically Endangered Hawaiian Native Worth Saving in Your Garden
Meet ‘akoko (Chamaesyce arnottiana), one of Hawaii’s most precious native plants that’s quietly disappearing from the landscape. This unassuming shrub might not grab headlines like a flashy hibiscus, but it’s got a compelling story that makes it absolutely worth considering for your Hawaiian garden—if you can find it responsibly sourced, that is.
What Makes ‘Akoko Special?
‘Akoko is a perennial shrub that’s as tough as it is rare. This multi-stemmed woody wonder typically grows 4-5 meters tall (that’s about 13-16 feet), though it can sometimes surprise you by growing taller or staying more compact depending on where it’s planted. Think of it as Hawaii’s answer to a desert plant—it’s built for survival in tough conditions.
The plant goes by several scientific names in the botanical world, including some tongue-twisters like Euphorbia arnottiana and Anisophyllum virgatum, but ‘akoko is much easier to remember and rolls off the tongue beautifully.
Where Does ‘Akoko Call Home?
‘Akoko is endemic to Hawaii, meaning it exists nowhere else on Earth. You’ll find it naturally growing throughout the Hawaiian Islands, where it has adapted to the unique coastal and dry forest environments that make Hawaii so special.

The Conservation Reality Check
Here’s where things get serious: ‘akoko has a Global Conservation Status of S1, which translates to Critically Imperiled. This means there are typically only five or fewer natural populations left, with fewer than 1,000 individual plants remaining in the wild. That’s… not great news.
Should you plant ‘akoko? Absolutely—but only if you can source it responsibly from reputable native plant nurseries or conservation programs. Never collect seeds or cuttings from wild populations. Think of yourself as joining a conservation effort rather than just adding another plant to your garden.
What ‘Akoko Brings to Your Garden
‘Akoko might be endangered, but it’s not high-maintenance. This shrub offers several compelling reasons to include it in your landscape:
- Drought tolerance: Once established, ‘akoko laughs in the face of dry conditions
- Native pollinator support: It attracts Hawaiian native insects and beneficial pollinators
- Low maintenance: Perfect for busy gardeners who want impact without constant fussing
- Conservation impact: You’re literally helping preserve a species
Growing ‘Akoko Successfully
Good news: ‘akoko wants to survive, which makes it relatively straightforward to grow in the right conditions.
Hardiness: This is strictly a tropical plant, thriving in USDA zones 10-11. If you’re not in Hawaii or a similar climate, ‘akoko probably isn’t for you.
Sun and Soil: Give ‘akoko full sun and well-draining soil. It’s adapted to coastal conditions, so it can handle sandy, rocky, or less-than-perfect soil as long as water doesn’t sit around the roots.
Water Wisely: Water regularly when first planted to help establish roots, then back off. Mature plants are quite drought-tolerant and prefer to dry out between waterings.
Care Tips for Happy ‘Akoko
- Protect young plants from strong winds until they’re established
- Watch for browsing animals—they sometimes find ‘akoko tasty
- Minimal fertilizer needed; too much can actually harm the plant
- Prune lightly if needed, but this plant generally maintains its shape well
The Perfect Garden Match
‘Akoko shines in native Hawaiian gardens, coastal landscapes, and xeriscape designs. It pairs beautifully with other Hawaiian natives and fits perfectly into conservation-minded landscapes. If you’re creating a garden that celebrates Hawaii’s unique ecosystem, ‘akoko deserves a place of honor.
The Bottom Line
‘Akoko represents both an opportunity and a responsibility. By growing this critically endangered native, you’re participating in conservation while adding a resilient, beautiful plant to your landscape. Just remember: source responsibly, grow thoughtfully, and take pride in knowing you’re helping preserve a piece of Hawaii’s natural heritage.
Sometimes the most important plants aren’t the showiest ones—they’re the ones that need our help the most.
