2011/2012/2013 Poinsettias!

These were my poinsettias from Christmas 2011!  The remaining two from the Costco three-pack I bought November 2011.  I have never had much luck with keeping poinsettias alive through Christmas, much less until now.  I thought they were pretty much goners after that Christmas and just tossed them (pots in all) in the far right corner and side of my kitchen garden.  I was surprised to see tiny leaves reappear on the stalks in the spring and felt certain our drought would finish them off.  But no, they kept growing, roots now attached firmly to the garden dirt.  Our crazy temperature changes must have triggered the color change.
