Stush, Put your plants outside immediately, if they are planted in loose soil that will drain well. You will love to see what they do after the snow melts in February/March. I think you are more likely in zone 5 most winters for plant planning purposes. Note that if they get too much shade in your area, they will be greenish for most of the year, but too much sun will make it harder to grow them but give great colors.
They need to be outside. If inside, do not water them and keep them cool/cold.
