Last Christmas I decided I was going to try to keep out poinsettias alive to have the following Christmas. I got the idea from this garden blog I follow:

I have three in the basement sheltered from all light, so they only get a few hours of light a day on a timer and then are in complete darkness for the rest of the time. One is starting to take color.
