Where in PA are you? The reason why I ask is because PA is climatically diverse. I mean, Coudersport is very cold in the winter, while Philly is significantly warmer. I used to live in Wyomissing, which is near Reading, which is NW of Philly and I have a friend who has an outdoor bog in his from lawn. His plants are out there all year long. He may mulch it for the winter, but I'm not sure. I can find out, though. The key to keeping plants through the winter, if kept outside, is to heavily mulch them. Otherwise, you can do as I have been doing - buckets of min-bogs. When Late fall hits and the temps are consistently going to be below freezing, I just tote the buckets to the attic and place them at the SW window sill. The attic is cold, but not frigid and the sunlight keeps them asleep. When late February comes around and the photoperiod has increased enough, the plants wake up naturally. By April, I tote them back outside.
