Sarracenias and VFT's need their winter rest.
Pinguiculas and Nepenthes do not go dormant. But make sure you use rainwater or distilled water. Though lately I notice my Pings do not mind our tap water. I have tested my Pings outdoors in our mild winter which goes down to the 30F range, and it endured well. Seems to grow nicely too since that is the time we get winter rains here. My Nepenthes has always stayed indoors by our sink, by a west facing window. Since my area is very dry, they like to be in standing distilled water.
