Mine grow outside and get whatever nature gives them. 5ºC/41 F is a fairly common winter night temperature for me... occasionally gets down to 2-3 deg C/35 deg. F most winters (for a few hours), much more rarely down to freezing (0 deg C/32 deg F), again for a few hours. They don't get any particular protection other than the shade cloth. They're fine. Like everything else, if temperatures are headed that low, it's better to keep them a bit drier than normal. If it rains, they get wet... but when it rains, the clouds usually keep the temperature a few degrees warmer.
