Garden Poinsettias

I was told that I could plant my potted Poinsettia from last year but it would not bloom in my garden because the ones they sell at Christmas are specially treated to bloom just that one Christmas and for gardens there is another species or variety. Well . . . they were half-way correct. Mine has three red petals (which are really leaves that turn red) and is nice in my garden, but not really the same as the big multi-red-leaves version I got before Christmas last year. And on my walks through town I also cellphone-snapped a photo of someone else’s Poinsettia which is obviously a different variety and probably one of the garden species that do bloom in the gardens. It is below this photo of the one in my garden . . .
