Hi Norm, there's not one simple answer because it also depends on how much sun and how warm the daytime high is. If you get a lot of sunny days that raise the daytime temp to 80F and above then it can go as cold as high 40's at night and still get some blooms. A more common scenario is lots of cloud cover and days that are also on the cool side. In that case 50F is the lowest and every 5 degrees warmer will give better results. I keep mine at 60F low during the winter and see growth and blooms at that temp.
