Metrosideros polymorpha is an extremely variable plant. It ranges in habit from a prostrate shrub to a 100 foot tree. Young bark is smooth and light gray and becomes rough and scaly with age. In the landscape or garden, Metrosideros polymorpha is generally no larger than 40 feet tall and 30 feet wide often with a broad, columnar silhouette. The leaves are generally oval in shape ranging in size from 1/2 to 3 inches long and 1/2 to 2 1/4 inches wide. The mature leaves are generally leathery and smooth dark green, but some forms are woolly or hairy underneath and may appear grayish. The leaf buds (liko) can range in color from pale green to pink to red. Metrosideros polymorpha blooms mostly in the spring, but can bloom sporadically throughout the year. Weissich notes that there can be as many as 3 blooming periods per year. The powder puff like flowers are most often a shade of red, but yellow, orange, salmon, and pink forms are also found.
This plant was growing beside the trail on a mountaintop on Kualoa Ranch.
