Rainbow Eucalyptus Seeds

Landscape Rating: ⭐⭐⭐⭐⭐ (5/5 Stars)

Plant Characteristics

Rainbow Eucalyptus is arguably the most spectacular ornamental tree in the world. Native to the tropical rainforests of the Philippines, Indonesia, and Papua New Guinea, this extraordinary species is famous for its brilliantly colored bark that naturally displays shades of green, blue, purple, orange, red, and maroon.

The remarkable coloration develops as the bark peels away in successive layers throughout the year. Newly exposed bark appears bright green and gradually matures through a dazzling spectrum of colors, creating the appearance that the trunk has been painted by hand.

Mature trees can reach 100 to 250 feet in their native habitats, though landscape specimens are often considerably smaller. The tree develops a tall, straight trunk, smooth bark, and an elegant evergreen canopy of glossy green leaves.

As a specimen lawn tree, Rainbow Eucalyptus creates one of the most unforgettable landscape displays found anywhere in the plant kingdom.

The flowers attract bees and other pollinating insects, while the canopy provides shelter and habitat for birds and wildlife.

In its native rainforest habitat, the tree contributes to complex tropical ecosystems and supports numerous species.

Seedman Landscape Note

Rainbow Eucalyptus may be the ultimate conversation-piece tree. Its naturally painted trunk creates a level of visual interest unmatched by virtually any other ornamental species grown in landscapes today.

Additional Seedman Note

Many people assume photographs of Rainbow Eucalyptus have been digitally enhanced, yet the remarkable bark colors are completely natural. As old bark peels away and fresh bark matures at different rates, the trunk continuously develops new combinations of green, blue, purple, orange, and red. The result is a living work of art that changes throughout the year and has earned Rainbow Eucalyptus a reputation as one of the most beautiful trees on Earth.
