This is a poinsettia growing in our neighbors yard. It wasn't there last June when we left, but I noticed it right away when we returned in January. It is at least four feet tall, maybe more. I read in my tropical flower book that poinsettias can reach a height of 12 feet or more if not trimmed. This one hasn't been. They will bloom almost continuously when cut back once or twice a year.
I wonder how tall it will get.
