Gorgeous eucalyptus with peeling bark that displays a rainbow of colors.

 The rainbow eucalyptus is an unusual tree with a beautiful trunk. The trunk periodically sheds a strip of bark, revealing a green layer underneath. This layer then changes colour. The shedding and colour change happen at different times in different parts of the trunk. In addition, a variety of new colours are produced. The overall effect is lovely and gives the tree its "rainbow" name.

We're used to beautiful colours in the flowers and fruits of trees and in their autumn leaves, but a coloured trunk is an oddity. The rainbow eucalyptus is greatly admired and is often planted deliberately, either for its appearance or for its other benefits. It's an interesting and impressive tree.
