For the first few years of growth, the colorful trunk may not be as apparent, especially if the bark has yet to begin shedding. There are other ways to identify the tree, such as the fuzzy, white flower clusters. These clusters have seven individual flowers that bloom in the spring. The fruits that form are small, brown, and capsule-shaped. Each fruit contains a few dozen seeds with an attached wing. While not as fragrant as other species, the foliage of rainbow eucalyptus still contains the characteristic aroma.
