Illawarra Flame Tree – Brachychiton acerifolius Plant
The Illawarra Flame Tree (Brachychiton acerifolius) is a distinctive ornamental tree known for its brilliant red flowers and attractive green leaves. Native to eastern Australia, it is valued for the bold colour it brings to spacious gardens, parks and landscape projects.
The tree is especially admired for its flowering display. Clusters of bright scarlet to red, bell-shaped flowers can cover the branches, sometimes appearing when much of the foliage has fallen. This creates a striking contrast between the colourful blooms and the tree’s bare branches. Flowering time and intensity depend on local weather, growing conditions and the maturity of the tree.
Its leaves add further interest, with shapes that can vary from simple outlines to deeply divided, hand-like forms. As the tree grows, it can develop a broad canopy, making it a suitable choice for landscape designs that need a prominent flowering tree rather than a small garden plant.

Growing and Care Requirements
Plant the Illawarra Flame Tree in a sunny, open location with well-drained soil. Water it regularly during the establishment period, allowing excess water to drain away rather than leaving the roots in waterlogged soil. Once established, it can tolerate some dry periods, although prolonged drought may affect its growth and flowering.
Provide enough space for the tree to develop its mature height and canopy. Under cultivation, it can reach approximately 10–15 metres, depending on the growing environment, and may grow taller in favourable conditions. It is therefore better suited to large outdoor spaces than small balconies, narrow courtyards or compact garden beds.
