Callistemon is an Australian shrub that makes amazing red flowers with the shape of a bottle brush, and that’s the common name of this plant: bottlebrush. It’s very simple to recognize them because of the very particular flower shape. In the wild this plant is a great resource for parrots, specially lorikeets! So, if we find one of these amazing shrubs in bloom, we should definitely cut a few branches and offer them to our birds!
