I am growing Sarracenia outside year around here in Reno. I have built inground bogs with flexible pond liner enabling me to make my bogs any size or shape to accommodate my landscaping. I was encouraged to start growing them here after reading all the information from Canadian growers.
In the fall, when the plants start dying back for the winter, I cover my bogs with 4 layers of burlap (its the desert - no pine needles). I leave the old pitchers on thus forming an air pocket below the burlap. Its not being frozen solid that kill the Sarracenia, but the freeze/thaw cycle we ofter see in the winter. I do have to lift a corner once in a while and add some water so they don't become desicated in the zero humidity and lack of rainfall. A pine needle cover with snow on top would keep the Sarracenia very happy. Don't pack the pine needles - leave them fluffy. I uncover them in the early spring when the low temps are in the upper 20's.
I have one Drosera living outside in the bog - I think it got there with others plants I purchased. It has survived two winters outside now. I know its not from my greenhouse because it blooms white.
Good article Tarev.
