The Rainbow Eucalyptus is a tree with bark so brightly colored that it is almost hard to believe that it is not an elaborate practical joke. This tree, native to the Philippines, sheds the outer layer of its bark often to expose new, green bark underneath. As the bark ages it goes through several color changes from green, to blue, to purple, to orange, and finally to brown before being shed. Because the bark is shed in irregular patches the tree displays a collection of all these colors at once giving a kaleidoscopic effect. They can be grown in many places which will not experience frosts but in the Philippines they are mostly cultivated for use in paper manufacture and not as decorative trees.
