Pūkiawe is also known as `ali`i mahu, Kamehameha styphelia, and Hawaiian heather. In the early 1800's, Berlin botanists Ludolf Karl Adelbert von Chamisso and Johann Friedrich Eschscholtz named the plant after King Kamehameha I when they returned home following an expedition to Hawai`i.
This perennial can grow between 1 foot high as a small shrub, and 15 feet high as a tree. On its thin narrow branches are many small oblong stiff leaves. The prickly leaves grow alternately along the hairy stem and are dark green on the top, with smoky white-green veins on the bottom. Tiny white flowers shaped like stars can be found hidden beneath the leaves. From the flowers, the berries appear. Pūkiawe berries are about ¼ inch round and grow in pink, burgundy red or white colors. They are not edible.
Pūkiawe flowers year-round. The plant prefers dry habitats and is one of the last plants found at high altitudes.
