Rainbow Eucalyptus tree in Hana, Hawaii
Why are you reporting this puzzle?
These trees may look like they’ve been painted on, but these colors are all natural. This spectacularly colored tree is called Eucalyptus deglupta, and also known as the Mindanao Gum or the Rainbow Gum tree. The multi-colored 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.
