Bottlebrush

Callistemon

A genus of close to 30 species of trees and shrubs within the larger Myrtacaceae family. They are all native to Australia.
They can be propagated from seed during fall or spring, or for the cultivars from semi-ripe cuttings taken during summer.
They are more winter hardy where summers are sunny and hot. Most species are tolerant of salt, lime, drought and wet soil though unfortunately many species do not like clay. Many species are preferrably cut back hard every few years to induce vigor.
The flowers attract nectar feeding birds such as Hummingbirds. The Bottlebrushes are deer resistant.
Freeze damaged plants can be cut back hard during early spring, even to the ground. They will often quickly regenerate.
