Rainbow Eucalyptus–The Most Colorful Tree on Earth

Rainbow eucalyptus is an evergreen tree with spear-shaped, silvery-green leaves and clusters of tiny white flowers. The most stunning feature is the trunk, which grows rainbow bark in shades of green, blue, orange, red, and purple. As it grows, the bark peels off in strips to reveal new colors and patterns, its beauty constantly evolving.

Only certain parts of the United States are home to rainbow eucalyptus trees because they need a consistently warm climate with plenty of rain to grow. San Diego, California, is becoming a destination to view the trees. You can see them at Balboa Park, along Sports Arena Boulevard, the San Diego Zoo, and parts of Mission Bay.

You'll find rainbow trees in certain parts of Hawaii, too. There's a famous grove of trees in Maui along the Hana Highway, and you can also spot them at Ke'anae Arboretum. On Kauai, you can stroll along the Princeville walking path to see groups of rainbow eucalyptus, and they're at the Wahiawa Botanical Garden and Honolulu Zoo on Oahu.
