Callistemon is a genus of 34 species of shrubs in the family Myrtaceae, all of which are endemic to Australia. Callistemon species are commonly referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional brush used to clean the interior of bottles. They are found in the more temperate regions of Australia, mostly along the east coast and south-west, and typically favour moist conditions so when planted in gardens thrive on regular watering. However, at least some of the species are drought-resistant. There are varieties with white, yellow, pink or red flowers.
Bottlebrushes are often planted on nature strips along Melbourne streets and are also a favourite garden tree. Around Christmas and all through the summer the showy flowers make quite a spectacular display and provide nectar for insects and native birds. This variety illustrated is Callistemon 'Wildfire' - a rounded shrub to 2m high by 2m wide with slightly pendulous branches. It has showy red clusters of brushy flowers.
