Rainbow Eucalyptus

Rainbow Eucalyptus (Eucalyptus deglupta)

Yes the tree bark really does look like that with beautiful colors.

Common Names: Rainbow Eucalyptus, Mindanao Gum, Rainbow Gum.

Best Growing Environment: Rainbow Eucalyptus prefers a tropical or subtropical climate where temperatures do not frequently dip below 50°F (10°C). They thrive in rich, medium to wet soil with good drainage. These trees appreciate consistent moisture, especially when they are young and establishing.

Average Height: The Rainbow Eucalyptus is a tall tree, often reaching heights of over 200 feet in its native habitat. However, in cultivation outside its natural environment, it typically grows between 100-125 feet.

Growth Rate: This species is known for its fast growth rate, especially in ideal conditions. It can grow up to 3 feet or more per year.

Sun Requirements: Rainbow Eucalyptus requires full sun to grow well and achieve its best coloration. Ample sunlight is vital for the tree's overall health and the development of its distinctive multicolored bark.

Cold Hardiness: While this tree loves tropical climates, it can tolerate occasional cold snaps down to about 32°F (0°C). Prolonged exposure to freezing temperatures can damage or kill the tree.

Water Requirements: The Rainbow Eucalyptus has moderate to high water requirements. While it's drought-tolerant once established, regular watering will promote the best growth, especially in the tree's early years. Its natural habitat is along riverbanks, which implies a preference for consistent moisture.

Fertilizing Guide: A balanced, slow-release fertilizer can be applied in the spring to support its rapid growth. Due to its fast growth rate, the Rainbow Eucalyptus can benefit from nutrients, especially in soils that lack essential minerals.

Planting Guide: Choose a site with full sun exposure and well-draining soil. Dig a hole twice as wide as the tree's root ball and as deep. If planting multiple trees, ensure ample space between each to accommodate their mature size. Place the tree in the hole, ensuring it's at the same depth it was in its container. Backfill the hole, water deeply, and add mulch around the base to retain soil moisture and suppress weeds.

USDA Zone: Rainbow Eucalyptus is best suited for USDA zones 10-11. While it can survive in zone 9, it will require protection during the coldest months.

The Rainbow Eucalyptus is celebrated for its stunning, multicolored bark, which peels away in strips to reveal a bright green layer that darkens and matures to reveal shades of blue, purple, orange, and maroon.
