Firewheel Tree description
The Firewheel Tree is a medium to large evergreen tree native to subtropical and tropical rainforests of eastern Australia, from northern New South Wales to Queensland. It is also found in Papua New Guinea. It features glossy, dark green leaves that are deeply lobed when young, gradually becoming broader and oval shaped with age. The standout feature is its striking red-orange flowers, which appear in perfectly circular clusters from summer through to early autumn, giving the appearance of a fiery wheel.
In warmer regions or ideal conditions, flowering may begin as early as late spring. The vibrant red to orange tubular flowers are highly ornamental and attract nectar-feeding birds and insects.
In cultivation, the Firewheel Tree typically grows to around 10–15 metres tall and 5–8 metres wide, although it can reach up to 30 metres in its natural habitat. Its upright growth habit and lush foliage make it an excellent feature or shade tree.
Climate
Sub-tropical, warm temperate
Plant cultivation & care
Choose a sunny to partly shaded spot with protection from strong winds, especially while the tree is young. A sheltered location helps replicate its natural rainforest conditions. The Firewheel Tree prefers deep, well-drained soils enriched with organic matter. Avoid heavy or poorly draining clay, which can lead to root rot. Will tolerate light frosts.
Water regularly while establishing. Once established, the Firewheel Tree is moderately drought tolerant but will flower best with consistent moisture during dry periods. Apply a slow-release, low-phosphorus fertiliser formulated for Australian natives in Spring and Summer. Mulch around the base to retain moisture and suppress weeds.
Plant use
Native gardens, low maintenance gardens, specimen tree in large gardens, rainforest-inspired gardens, parks, public gardens, street trees, attracting birds and bees
Pruning
Minimal pruning is required. Simply remove any dead, damaged or crossing branches to maintain a neat structure.
Pests & diseases
No specific pests or diseases. Root rot can occur in waterlogged soils, so good drainage is essential.
