Yes, I know, the Poinsettia is the unofficial red flowering plant of the Christmas season — in Mexico, it even shares the name for Christmas Eve, Nochebuena. However, there is another red flowering plant that provides holiday color this time of year, the Bottle Brush tree (genus, Callistemon).
On the rooftop, my container-planted Bottle Brush tree.
Any way you look at it, it brightens the day and brings a bit of Christmas cheer to the garden.
Bottle Brush, the other red of Christmas!
