About

The Brachychiton acerifolius, commonly referred to as the Illawarra Flame Tree, is a tropical evergreen species that can grow up to 35 meters tall. This tree is distinguished by its large, terminal clusters of bowl-shaped, coral-red flowers, which can reach up to 2 centimeters in diameter and bloom in the summer. Following the flowering period, the tree develops leathery, glossy leaves that are bright green and typically palmate, measuring up to 20 centimeters in length with 3 to 5 lobes.

About the genus

Brachychiton comprises approximately 31 species of dome-forming trees or substantial shrubs, primarily found in Australia. Certain species feature thickened trunks, and the majority display clusters of bell-shaped flowers in shades of crimson, cream, or pink during the spring season.
