Important Conservation Considerations

Before you rush out to plant ‘ena’ena, there’s something important to know: this species has a Global Conservation Status of S3T3, indicating it faces some conservation concerns. This means that while it’s not critically endangered, ‘ena’ena populations deserve our attention and protection. If you choose to grow this plant, please ensure you source it from reputable native plant nurseries that propagate from ethically collected seeds or cuttings rather than wild-harvesting.

Why Garden with ‘Ena’ena

There are several compelling reasons to include ‘ena’ena in your Pacific island garden:

  • Supports native Hawaiian ecosystems and biodiversity
  • Attracts native pollinators and beneficial insects
  • Requires minimal water once established, making it drought-tolerant
  • Adds unique texture and color with its silvery foliage and yellow blooms
  • Connects your garden to Hawaii’s cultural and natural heritage
  • Low maintenance once established in suitable conditions

Perfect Garden Settings for ‘Ena’ena

‘Ena’ena shines in native Hawaiian plant gardens, restoration landscapes, and xerophytic (dry-climate) garden designs. It works beautifully as a ground cover or accent plant in naturalistic settings. This versatile native pairs well with other indigenous Hawaiian plants and thrives in gardens that celebrate the islands’ unique flora.

Growing Conditions and Care

‘Ena’ena is surprisingly adaptable and relatively easy to grow when given the right conditions:

  • Climate: Thrives in USDA hardiness zones 9-11, perfect for tropical and subtropical climates
  • Sunlight: Prefers full sun to partial shade
  • Soil: Well-draining soils are essential; avoid waterlogged conditions
  • Water: Drought tolerant once established, but benefits from occasional deep watering during dry periods
  • Maintenance: Generally low maintenance with minimal pruning needed

Planting and Establishment Tips

When planting ‘ena’ena, choose a location with good drainage and adequate sunlight. Plant in spring or early summer to give the roots time to establish before any challenging weather. Water regularly during the first few months after planting, then gradually reduce watering as the plant becomes established. The species may self-seed under favorable conditions, potentially creating natural colonies over time.

Supporting Native Hawaiian Heritage

By choosing to grow ‘ena’ena, you’re not just adding a beautiful plant to your garden—you’re participating in the preservation of Hawaii’s botanical heritage. This native species has been part of the Hawaiian landscape for countless generations, and cultivating it helps ensure its continued survival while creating habitat for native wildlife.
