How cold is too cold?

What is the lower range temperate butterworts can stand? I have some P. vulgaris seedlings and they're indoors in a cold windowsill now, but they were outside in -5 to -10 weather. Add in the windchill and it was down to -15. I'm just wondering so they don't die on me if I move them back outside. Thanks in advance!
