On Callistemon

Bottle brush is one of those common native trees that's easy to overlook for most of the year.The foliage is green and spiky, but a bit ordinary. The bark and the trunk certainly do their job OK, but again, nothing special to look at.
But when those long bright red bottle-brush flowers start to come out, it becomes very difficult not to notice them.
Not just because of the flowers' stand-out looks, but also because so many different birds - and a little later, bees - suddenly start paying the tree a serious amount of attention. Think the initial comings and goings of the first responders seems to have a powerful demonstration effect on further nectar-seekers, and they on others, and so on until the entire tree is fairly brimming with winged wildlife.
The Callistemon genus was originally classified as part of the Myrtacaea family, but more recently the botany boffins can't decide whether or not they might all belong to the Melaleucas genus instead.
Whichever genus it technically belongs to, don't think it really matters to these plants. When they're in full bloom and swarming with nectar-seekers, don't think they have any doubts about their true identity.
