A genus of trees and large shrubs native to Australia and New Guinea, known for species with showy flowers like the red-flowered Illawarra Flame Tree or the swollen trunk of the Broad-leaved Bottle Tree. They are generally drought-tolerant once established, thrive in sunny locations, and often have non-invasive root systems, making them suitable for urban landscapes.
