Living Rainbow: Rainbow Eucalyptus, Most Beautiful Tree.

I'd never heard of this tree. It truly is a work of art.
Living Rainbow: Rainbow Eucalyptus, Most Beautiful Tree Bark on Earth [36 PICS]

While this may appear to be a cool tree with camouflaged bark, it actually continues to morph in all the colors of a rainbow. If you enjoy the forest, then you probably like trees. This isn't Somewhere Over the Rainbow, but somewhere under the rainbow, so if you don't live in a warm, moist climate, then you might not have ever come across the most beautiful bark of any tree on Earth. With bright and uniquely-colored trunk and branches, the Rainbow Eucalyptus is "one of the most amazingly colorful species of tree," noted the photographer. Photo #1 by Roberto Verzo

The bark is smooth, but flaky as it sheds layers on various places at different times along the tree, revealing new colors and keeping up the appearance of a rainbow. The landscaping article Under the Rainbow (.pdf) explained, "As the newly exposed bark slowly ages, it changes from bright green to a darker green, then bluish to purplish, and then pink-orange. Finally, the color becomes a brownish maroon right before exfoliation occurs. Since this process is happening in different zones of the trunk and in different stages, simultaneously, the colors are varied and almost constantly changing. As a result, the tree will never have the same color pattern twice, making it like a work of living art." Photo #2 by juicyfunpark

This uniquely-shaped tree was in a small eucalyptus grove along the way to Hana, Maui. The eucalyptus deglupta is called by many names, most commonly the rainbow eucalyptus. Since it is believed to have originated in the Philippines, specifically the island of Mindanao, it is also called Mindanao gum or rainbow gum. Photo #3 by Chad Podoski

"One of the best places to see the Rainbow Eucalyptus trees is on the road to the windward town of Hana," reported the Examiner. "This famous, curvy road with over 600 tight turns and 53 one-lane bridges hosts several groups of the beautiful, colorful trees." Photo #4 by thaths

It can grow 8 feet a year, reaching a height of 197 – 246 feet (60 – 75 meters) with a diameter up to 7.9 feet (240 centimeters) wide. Photo #5 by Amelia Leubscher

"Bark from a rainbow eucalyptus … possibly one of the coolest trees on earth," noted the photographer. Photo #6 by Chad Podoski

However the World Agro Forestry Center states the following geographic distribution: the trees are native to Indonesia, Papua New Guinea, and the Philippines. Grown but considered exotic in Brazil, Congo, Costa Rica, Cote d'Ivoire, Cuba, Fiji, Honduras, Malaysia, Puerto Rico, Samoa, Solomon Islands, Sri Lanka, Taiwan, and the Province of China.

Sunshine and rainbows. This is a sun-loving tree that "does not grows naturally in areas with a pronounced dry season but occurs in those where the annual rainfall is very high and the monthly rainfall usually exceeds 150 mm. Because of this, it is widely planted throughout the wet tropics. E. deglupta does not withstand prolonged flooding, is highly sensitive to fires and, although it may grow in cool environments, it does not tolerate frost. Photo #11 by Lydia Mann

Magical looking forests: The multi-colored streaks of the trunks make these trees a distinctive landscape design element. If you'd like to have one, like we would, then in the United States the trees are only shipped to zones 9 and 10, meaning the lowest possible temperatures are 20 – 30°F. The rainbow eucalyptus is supposed to grow best in areas where the temperature averages about 73 – 88ºF (3 – 31ºC). Photo #16 by davecobb

The same tree can appear different, morphing as it sheds patches of showy bark at different times throughout the year. When wet, such as after a rain, the bark takes on a shiny coloring. Photo #17 by Jay Hickey


Grown around the world in tree plantations, the rainbow eucalyptus is mainly used for pulpwood in making white paper. It is the dominant species used for pulpwood plantations in the Philippines, but coffee farmers in Costa Rica are using the shade of this tree to effectively grow their coffee. Also the wood from the tree can be used to make furniture and cabinets and sometimes for construction. In Hawaii, the rainbow eucalyptus is also used for making boats.

Looking up at the cool bark. Bob Beck, a tree expert at Zoo Miami stated, "This tree is the main source of food for the koala, and is where it makes its home, usually just going to the ground to get to the next tree where there might be a mate." Photo #19 by Andy Beal

Rainbow upon rainbow tree. The owner and one of the sellers for this tree said (.pdf), "Water is the single most important need these trees have. They must never be allowed to dry out, either in the pot or in the ground. If you keep them moist, they will reward you with rapid growth and more spectacular trunk coloration."

If you were to examine the roots of this tree, you'd see that they don't have the same colorfully striped-rainbow pattern as the bark does. Photo #24 by Jeff Kubina
