Love these trees when I was in Hawaii! Rainbow Eucalyptus trees in Kauai, Hawaii. This plant is beautiful and grows well in central Florida. I planted one 5 ft tall 5 years ago and now it is now 40 ft tall! It is also self pruning!
Rainbow Eucalyptus ~ Hana, Maui, Hawaii. The unusual phenomenon is caused by patches of bark shedding at different times. The different colours are therefore indicators of the age of the bark: Freshly shed outer bark will reveal the bright green inner bark. This darkens over time and changes from blue to purple and then reaches orange and maroon tones.
Rainbow Eucalyptus Tree - 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.
