Eucalyptus deglupta is a tall tree, commonly known as the rainbow eucalyptus, Mindanao gum, or rainbow gum.
It is found in an area that spans New Britain, New Guinea, Seram, Sulawesi, and Mindanao. It thrives in tropical forests that get a lot of rain.
It is called rainbow eucalyptus because of the unique multi-hued bark. It's the inner bark that reveals a spectrum of incredible colours-oranges, maroons, even blues.
Patches of outer bark are shed annually at different times, showing a bright green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones. The previous season’s bark peels off in strips to reveal a brightly coloured new bark below. The peeling process results in vertical streaks of red, orange, green, blue and gray.
It is cultivated as an ornamental tree and mainly for pulpwood used in making white paper.
