The species exhibits remarkable morphological diversity, ranging from prostrate shrubs in bogs to towering trees reaching 30 meters (98 feet) in height on favorable sites. This variation is reflected in its scientific name &#8220;polymorpha,&#8221; meaning &#8220;many forms.&#8221;<\/p>\n<p>The tree produces brilliant clusters of flowers made up of masses of stamens that give the blossoms their characteristic pompom appearance. Flower colors range from the most common fiery red to yellow, orange, salmon, pink, and cream. The leaves are oval-shaped and may appear woolly, with distinctive eye-catching young leaf buds (liko) that vary between individual trees. The bark is light gray and rough, becoming twisted as the tree grows.<\/p>\n<p>`Ohi`a is extremely hardy and adaptable, capable of growing from sea level to elevations of 2,500 meters (8,200 feet). It tolerates a wide range of soil conditions and can survive in areas receiving as little as 400mm of annual rainfall or as much as 10,000mm in wet bogs. The tree is typically one of the first species to colonize new lava flows.<br \/>\n<a href=\"#top\"><font size=\"-2\">Back to Top<\/font><\/a><\/p>\n<hr size=3 width=80% COLOR=\"#004040\" align=\"center\">\n<h3><a name=\"Where\">Where Found<\/a><\/h3>\n<p><img decoding=\"async\" src=\"http:\/\/medicinalherbinfo.org\/000Herbs2016\/wp-content\/uploads\/2025\/05\/11-Metrosideros_polymorpha.jpg\" alt=\"Metrosideros polymorpha\" align=\"right\" style=\"width:400px;height:auto\"\/><\/p>\n<p>`Ohi`a Lehua is endemic to the six largest Hawaiian Islands: Hawai`i (Big Island), Maui, Moloka`i, L\u0101na`i, O`ahu, and Kaua`i.

When the volcano goddess Pele fell in love with the handsome `Ohi`a and he refused her advances, she transformed him into a tree in jealousy. The devastated Lehua was then transformed by the other gods into a flower and placed upon the `Ohi`a tree so the lovers could be reunited forever.
