Our red bottlebrush (Callistemon) has joined the mango (now just about finished), paperbark, poplar gum and macadamia in bursting into flower. It is far smaller than the first three, although still three or four metres high, and the flowers are attractive to the birds as well as to us.
I have seen Friarbirds feeding on the blossom, too, and a few insects – native bees, for instance.
