Looks like I will flower it in the cold bulb/alpine house area but put it back in the frost free section as soon as it gets threatened. I have never had the white forms seed around like the red, although I have grown it at various times. Maybe I sent all the white form (yellow) seed to seedex's. It has been cold enough to hit the "New Guinea Impatiens" here but nothing worse yet. The Begonia boliviensis is looking a bit less vigorous now. Thank you for all the comments.
