Meomye, I keep mine out over winter incl. tender ones...mind you it is sunny....er wet..Cornwall. Always take cuttings.
I have a trough full of sunpatiens and another of yellow voltage osteospermums looking just fine. The former will disappear but the osteos will comtinue.
you can still take cuttings and keep your plants in pots for as long as you want to. A mild winter and they might survive but so far nobody has had any signs of cold weather I think. If the forecasf is for frost that is the time to bring in your plants
