These colorful trees look as though someone painted them, however they are naturally like this, with peeling bark revealing these unique colors, and only indigenous to the northern hemisphere, growing in the Philippines, New Guinea and Indonesia. Thanks to the tropical forests that receive a lot of rain, the rainbow eucalyptus is able to thrive and can grow up to 250 feet tall. Of course, the most special thing about these trees is its bark. The previous seasons bark peels off in strips revealing brightly colored new bark. The peeling results in vertical streaks of red, orange, green and blue and is a sight to see. Besides the climate they live in, the rainbow eucalyptus growing include full sun and moist soil. So if you live in an area that receives plenty of rain and frost-free, you can actually grow your own rainbow eucalyptus tree.
