Poinsettia in a Can

If you're looking for holiday houseplants there are better options than poinsettias. As much as I dislike poinsettias, I couldn't resist buying this poinsettia in a can when I came across it at the dollar store the other day. Technically, it isn't a gag gift, and there is no poinsettia crammed inside of this can. At least not yet.
