This begonia has been growing in a pot all summer. I don't know what kind it is and wondered if it is a tuberous begonia that I can save. I brought it inside today because we are expecting a frost tonight (western PA). We will spend the winter in southwest Florida and if it is a tuberous begonia, I thought I'd dig it out of the pot and take it with me to re-pot. The plant is over 3 feet wide and 2 feet tall, so I can't take the whole thing in the car.

Thanks for your help.
