We currently have 22 that we bought this year - our Home depot does a promotion on the Friday after Thanksgiving where they sell 6" pots of them for $1 a piece while supplies lasts. We always get our trees that day and also load up on poinsettias.
I also have about 6 or 8 poinsettias outside that I've had over the last several years. If I remember to put the. On the side of the house with no lighting at night they color up well! I also have a variegated poinsettia that I LOVE!
