Hawai’i Alectryon: A Rare Native Gem Worth Preserving in Your Garden
If you’re passionate about native Hawaiian plants and conservation, the Hawai’i alectryon (Alectryon macrococcus var. macrococcus) might just capture your heart. This remarkable native tree offers both beauty and ecological significance, though its rarity makes it a special responsibility for any gardener lucky enough to grow it.
What Makes Hawai’i Alectryon Special?
The Hawai’i alectryon is a perennial tree that’s exclusively native to the Hawaiian Islands. Also known by its synonym Alectryon mahoe, this woody beauty typically grows as a single-stemmed tree reaching heights of 13 to 16 feet or more, though environmental conditions can sometimes result in shorter, multi-stemmed growth forms.
What really sets this tree apart is its stunning fruit display. The Hawai’i alectryon produces eye-catching capsules that split open to reveal glossy black seeds adorned with bright red arils – nature’s own jewelry box! The compound leaves add year-round visual interest, making this tree a true four-season performer in tropical and subtropical gardens.
Where Does It Grow?
This endemic Hawaiian species is found only in Hawaii, where it has evolved specifically to thrive in the islands’ unique climate and ecosystem conditions.
A Word of Caution: This Plant is Rare
Important conservation note: The Hawai’i alectryon has a Global Conservation Status of S1T1, meaning it’s critically imperiled. If you’re interested in growing this beautiful native tree, it’s crucial to source your plant material responsibly from reputable native plant nurseries or conservation programs. Never collect plants from the wild, as this could further threaten wild populations.
Why Grow Hawai’i Alectryon?
Despite its rarity – or perhaps because of it – there are compelling reasons to include this tree in appropriate gardens:
- Conservation impact: By growing this rare native in your garden, you’re helping preserve Hawaiian biodiversity
- Unique beauty: The striking fruit display and attractive foliage make it a genuine conversation starter

Growing Conditions and Care
The Hawai’i alectryon is surprisingly adaptable once you understand its needs:

Once established, this native beauty is refreshingly low-maintenance:
- Drought-tolerant once the root system is established (usually after the first year)
- Water regularly during the establishment period
- Minimal pruning needed – just remove dead or damaged branches
- Watch for any signs of stress and adjust care accordingly
Perfect Garden Roles
The Hawai’i alectryon shines in several garden settings:
- Specimen tree: Its unique fruit makes it a natural focal point

- Drought-tolerant landscapes: Great for water-wise gardening once established
Supporting Conservation Through Gardening
By choosing to grow the Hawai’i alectryon, you’re not just adding a beautiful tree to your landscape – you’re becoming part of a conservation effort. This rare native deserves a place in more gardens, but only when grown from responsibly sourced material.
When purchasing your tree, ask nurseries about their sourcing practices and look for plants that are part of legitimate conservation or restoration programs. Your garden can become a living seed bank, helping ensure this remarkable Hawaiian native continues to grace the islands for generations to come.
