I dont think so Alexis. Our winters are much too cold I think. I left a purp outside last year and it completely devastated it. The low last winter hit about -20F (-28C)with wind chill. I dont think the tissue from the flower would survive since the purp pitchers didnt.

I also would prefer the plant to flower in unison with the others so that I could cross pollinate in the spring.
If I had the chance to live in zone 7-8 I'm sure there could be a possibility that seed would set in winter, but since I place all Sarrs in fridge dormancy and I'm low on space, I couldnt accommodate a flower. I also did not have any pollen to use for cross pollination and did not want to mess with selfing the flower.
