Easily recognizable and aptly named, the Rainbow Eucalyptus Tree is called that because of its multi-colored bark. Many people mistake the abstract strokes of color for paint, but this beautiful tree naturally bears many shades of colors like green, orange, purple, brown, pink and blue. What makes them even more special and truly unique is that no two trees have the same pattern. Because of the gorgeous “rainbow” colored bark, this tree is often grown for decorative purposes to create a vibrant scenery. Patches of the outer bark are shed annually, exposing the bright green inner bark. Over time, it darkens to produce the blue, purple, orange and maroon hues. The colorful bark tends to outshine the tree’s flowers, which are very subtle and often go unnoticed. Up close, the flowers are pretty, white stamens with flowered clusters. One of the reasons the flowers are usually overlooked is because they are hard to see on such large, tall trees. The Rainbow Eucalyptus Tree can grow between five to eight feet every year. They can get as tall as 220 feet, and the trunk of the tree can even get as thick as six to eight feet around! In its native habitat, this huge tree serves as both food and a home to koalas. While it is native to Australia, New Guinea and Tasmania, the striking Rainbow Eucalyptus Tree can be found right here in Australia at Zoo Miami.
