Illawarra Flame Tree
Another red-flowering native, this tree loses its leaves just before flowering and, in a good season, can be a towering pillar of red.
Stenocarpus (Queensland Firewheel Tree)
At blooming time, this rainforest tree looks as if it's lit up from within by the red pinwheel flowers that cluster among its branches.
Gordonia
On the borderline between a tree and a shrub, but able to be pruned into a tree-like shape (which shows off its attractive bark), gordonia's 'fried egg' flowers can be close to 10cm across.
Jacaranda
This glorious South American native usually flowers when the tree is bare of leaves, which enhances the magnificent effect.
Magnolia
Another tree that usually blooms on bare branches, every deciduous magnolia is a garden aristocrat.
