#AmazingPlanet These trees may look like they've been painted on, but these colors are all natural. This peculiar tree is called Eucalyptus deglupta, commonly known as the Rainbow Eucalyptus. 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. Also, its natural distribution spans New Britain, New Guinea, Seram, Sulawesiand Mindanao.
