`Bottlebrush` flower has the exact appearance of its name. There are many colours, and this bright red is common in most of the coastal areas of eastern Australia. Birds love the tree and these flowers, and I watch many parrots in our garden tree, when flowers are blooming.

Bottlebrushes are members of the genus Callistemon and belong to the family Myrtaceae. They are closely related to paperbark melaleucas, which also have `bottlebrush` shaped flower spikes. It is difficult to tell to which genus some species belong. Botanists are currently closely studying these plants to determine how they are best classified. There are 34 species currently called Callistemon.
