‘Ekoko: A Hidden Gem for Hawaiian Native Gardens

Meet ‘ekoko (Chamaesyce celastroides var. celastroides), a charming native Hawaiian shrub that deserves a spot in every island gardener’s heart—and landscape. While it may not win any beauty contests with flashy flowers, this understated perennial has plenty of character and some serious practical benefits that make it worth getting to know.

What Is ‘Ekoko?

‘Ekoko is a native Hawaiian shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet in height. Think of it as nature’s way of creating a low-maintenance, drought-smart addition to your garden. This perennial belongs to the spurge family and has adapted beautifully to Hawaii’s unique climate conditions over thousands of years.

Where Does ‘Ekoko Call Home?

This plant is a true Hawaiian endemic, meaning it evolved right here in the islands and exists nowhere else on Earth naturally. You’ll find it growing throughout Hawaii, where it has learned to thrive in the islands’ diverse microclimates.

Important Conservation Note

Here’s something every responsible gardener should know: ‘ekoko has a Global Conservation Status of S3T3, which indicates it faces some conservation challenges. This doesn’t mean you can’t grow it, but it does mean you should be thoughtful about sourcing. Always purchase from reputable native plant nurseries that grow their stock from ethically collected seeds or cuttings, rather than wild-harvesting plants.

Why Choose ‘Ekoko for Your Garden?

While ‘ekoko might not be the showiest plant in your garden, it brings several valuable qualities to the table:

  • Authentically Hawaiian: Supporting native plants helps preserve Hawaii’s unique botanical heritage
  • Drought-smart: Once established, it handles dry conditions like a champ
  • Low maintenance: Perfect for busy gardeners or those who prefer a more natural landscape approach
  • Erosion control: Its root system helps stabilize soil, especially useful on slopes
  • Wildlife support: Native plants generally support native insects and birds better than non-natives

Perfect Garden Situations for ‘Ekoko

‘Ekoko shines in several garden scenarios:

  • Native Hawaiian landscapes: Essential for anyone creating an authentic island garden
  • Xeriscaping projects: Excellent choice for water-wise landscaping
  • Coastal gardens: Handles salt spray and sandy conditions well
  • Rock gardens: Thrives in well-draining, rocky conditions
  • Slope stabilization: Great for preventing erosion on hillsides

Growing Conditions That Make ‘Ekoko Happy

The good news is that ‘ekoko isn’t particularly fussy, but it does have some preferences:

  • Sunlight: Full sun to partial shade works well
  • Soil: Well-draining soil is crucial—think sandy or rocky rather than clay
  • Water: Drought-tolerant once established, but appreciates occasional watering during very dry spells
  • Climate: Thrives in USDA hardiness zones 10-12 (basically tropical and subtropical areas)

Planting and Care Tips

Growing ‘ekoko successfully is refreshingly straightforward:

  • Site selection: Choose a spot with good drainage—waterlogged roots are this plant’s kryptonite
  • Planting: Dig a hole slightly wider than the root ball but no deeper, and backfill with native soil
  • Initial watering: Water regularly for the first few months while the plant establishes
  • Ongoing care: Once established, water only during extended dry periods
  • Pruning: Light pruning to maintain shape is fine, but not necessary
  • Fertilizing: Generally unnecessary—native plants prefer lean soils

Special Considerations

‘Ekoko has a Facultative Upland wetland status in Hawaii, meaning it usually prefers non-wetland conditions but can occasionally tolerate wetter spots. This makes it quite versatile for different garden situations, though it’s happiest in well-draining areas.

The Bottom Line

If you’re gardening in tropical zones and want to support native Hawaiian flora, ‘ekoko deserves serious consideration. It’s not the most dramatic plant you’ll ever grow, but it’s reliable, authentic, and plays an important role in Hawaii’s ecosystem. Just remember to source it responsibly from reputable native plant growers, and you’ll have a piece of true Hawaiian natural heritage growing in your own backyard.

Sometimes the most rewarding plants aren’t the flashiest ones—they’re the ones that connect us to the place we call home.
