Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalized in scattered locations.
Callistemon species are commonly referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush.
Callistemons can be propagated either by cuttings (some species more easily than others), or from the seeds. Flowering is normally in spring and early summer
