This annual geranium (Pelargonium) bloomed on my outdoor deck all Summer and persisted through Fall. It is now December 6 and the high temp today was only 34 degrees. This annual is still very alive and still has light pink flowers coming up. The water in my fountain is frozen so I don't know why this tender annual never died through the several frosts we've had.
