If you’re passionate about Hawaiian native plants and conservation gardening, you’ve probably heard whispers about ‘ohe makai. This remarkable tree, scientifically known as Reynoldsia sandwicensis, is one of Hawaii’s most precious botanical treasures – and unfortunately, one of its rarest.

A Conservation Concern

Here’s where things get serious, folks. ‘Ohe makai has a Global Conservation Status of S2, which translates to Imperiled. This means the species is extremely rare, with typically only 6 to 20 occurrences remaining and fewer than 1,000 to 3,000 individual plants left in the wild. This rarity makes every single ‘ohe makai tree incredibly precious.

Important: If you’re considering adding this tree to your garden, please only source it from reputable native plant nurseries that propagate from legally and ethically collected seeds or cuttings. Never collect from wild populations – they need every individual to survive.

Why Grow ‘Ohe Makai?

Despite its rarity (or perhaps because of it), there are compelling reasons to consider this native Hawaiian tree:

  • Conservation impact: Every responsibly grown tree contributes to species preservation
  • Cultural significance: You’re growing a piece of authentic Hawaiian heritage
  • Unique beauty: Its distinctive foliage creates an unmistakable tropical look
  • Native ecosystem support: Provides habitat and nectar for native Hawaiian insects
  • Conversation starter: A rare tree that’s sure to intrigue visitors

Growing Conditions and Care

‘Ohe makai thrives in tropical conditions, making it suitable for USDA hardiness zones 10-12 only. If you live outside these zones, this tree isn’t for you – it simply can’t tolerate cold temperatures.

For successful cultivation, provide:

  • Climate: Warm, tropical conditions year-round
  • Light: Partial shade to full sun
  • Soil: Moist, well-draining soil
  • Water: Consistent moisture without waterlogging
  • Protection: Shelter from strong winds that could damage branches

Landscape Design Ideas

‘Ohe makai works beautifully as a specimen tree in tropical gardens, Hawaiian native plant collections, or conservation-focused landscapes. Its moderate size makes it suitable for residential gardens, while its rarity gives it special status in botanical collections or educational gardens.

The Bottom Line

‘Ohe makai represents both an opportunity and a responsibility. While it’s a gorgeous addition to any tropical garden, its imperiled status means we must approach it with respect and care. If you decide to grow this rare beauty, source it responsibly and consider yourself a guardian of Hawaiian botanical heritage.

Remember, every ‘ohe makai tree grown in cultivation is potentially one more step back from the brink of extinction – and that’s a pretty amazing legacy to have growing in your backyard.

Reynoldsia sandwicensis is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Reynoldsia sandwicensis is also known as:

Reynoldsia degeneri | USDA symbol: REDE
Reynoldsia hillebrandii | USDA symbol: REHI
Reynoldsia hosakana | USDA symbol: REHO
Reynoldsia huehuensis | USDA symbol: REHU
Reynoldsia huehuensis Sherff var. brevipes | USDA symbol: REHUB
Reynoldsia huehuensis Sherff var. intermedia | USDA symbol: REHUI
Reynoldsia mauiensis | USDA symbol: REMA
Reynoldsia mauiensis Sherff var. macrocarpa & | USDA symbol: REMAM
Reynoldsia oblonga | USDA symbol: REOB
Reynoldsia sandwicensis Gray var. intercedens | USDA symbol: RESAI

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
