This is the most classic tall heirloom poinsettia which is so widespread in the old gardens of the Canary Islands and the Southern Mediterranean. It is much hardier to anything than all the modern dwarf cultivars and in places with little or no frost, they are planted in rows with Nerium oleander (!) . Bracts are much simpler, often with straight margins or with just a few teeth. It typically blooms in mid-november and it is chopped back to 20-60 cm from the ground in january. Then they sprout new upright "canes" as the weather warms up.
