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, and also known as the Mindanao Gum, or the Rainbow Gum. The multi-coloured streaks on its trunk comes from patches of outer bark that are shed annually at different times, showing the bright-green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones.
Eucalyptus deglupta is the only Eucalyptus species found naturally in the Northern Hemisphere. It grows naturally in New Britain, New Guinea, Ceram, Sulawesi and Mindanao. Now, this tree is cultivated widely around the world, mainly for pulpwood used in making paper, and also for ornamental purposes.
