I brought a Geranium with red-splotched leaves indoors from my deck and another from my mother-in-law's when it started to get cold overnight. I planned to let them go dormant and then "resuscitate" them in the Spring. But they've never stopped growing. And they haven't been attacked by any of the usual indoor winter plant pests — at least so far. This Geranium even includes a clump of Tiarella in the pot with it that has continued to look beautiful all winter and is now sending out runners! You can see its dark green leaves in the back of the pot.
