Growing ‘Ohi’a Lehua: Hawaii’s Sacred Native Treasure
If you’re lucky enough to garden in Hawaii’s tropical paradise, there’s one native plant that deserves a special place in your landscape: the magnificent ‘ohi’a lehua (Metrosideros polymorpha var. newellii). This isn’t just any ordinary shrub – it’s a living piece of Hawaiian culture and ecology that brings both beauty and deep meaning to your garden.
What Makes ‘Ohi’a Lehua Special?
‘Ohi’a lehua is a perennial shrub that typically grows as a multi-stemmed woody plant, usually reaching heights of 13 to 16 feet, though it can sometimes grow taller or develop a single stem depending on growing conditions.

This particular variety, known botanically as Metrosideros polymorpha var. newellii (with the synonym Metrosideros collina var. newellii), is endemic to Hawaii, meaning you won’t find it growing wild anywhere else on Earth.

Important Conservation Note
Before you rush to plant ‘ohi’a lehua, there’s something crucial to know: this variety has a conservation status of S5T3, indicating it faces some population pressures.
