This genus is composed of trees and shrubs native to Australia. They are characterized by their bright, bristly, bottlebrush-like spikes of flowers in shades of mostly red, but also white, yellow, orange, and pink.
CareMost bottlebrushes are hardy in USDA Hardiness Zones 10 to 11. Provide full sun and fertile, moist, well-drained soil. Deadhead regularly and prune out any wayward stems. Hard pruning is tolerated.
Propagation Sow seed in spring or root cuttings in summer.
Problems Spidermites and scale may occur. Galls, cankers, and leaf spots may also become problems.
