Callistemon / Bottlebrush
Callistemon is a genus of around 30 species in the Myrtle family (Myrtaceae). All except four species are endemic to Australia, the others occurring in New Caledonia. Callistemons are commonly known as “bottlebrushes” because of the cylindrical, brush-like shape of the flower spike. They are very popular for gardens and landscaping both in Australia and overseas and numerous cultivars have been brought into cultivation.
