In my experience, Sarracenia are tough plants capable of weathering very cold temperatures with adequate winter protection. Here in zone 7a in New Jersey, I've successfully overwintered Sarracenia ranging from cold-hardy S. purpurea to a particularly sensitive S. (rubra x psittacina) x leucophylla hybrid. Winters here can get down to 10F. I've found that the secret to my success is large pots and lots of pine needles. I have my Sarracenia growing in large planters that I sink into the ground, then mulch with a one foot deep layer of pine needles. Additionally, the plants are covered by a protective snow blanket all winter, so I rarely lose anything to cold damage. I think that if you pick tougher plants like S. flava or S. oreophila and keep them under a thick layer of mulch in your shed, you should be fine. If you really want to get your hands on a S. psittacina, then I think your best bet is to just stick it in the fridge when dormancy comes around.
Sashoke, are you able to put them in the ground?
S. leucophylla are pretty tough, too.
I grow quite a variety of Sarracenia outdoors (Zone 5) year round. Around thanksgiving, I bury them under a mountain of mulch, leaves, etc. Even my S. minor was fine (if a bit slower to take off in the spring than everyone else.)
In addition to my S. purpurea, my S. psittacina, my mystery Sarracenia (I believe it is S. alata) S. minor, S. leucophylla, all survived last winter, and that was a doozy, and their first winter outdoors to boot.
This year I have dozens more out there, but I don't want to say for sure how they did until spring, lol. Even though this winter has so far been much milder than last winter.

No I dont think Im able to put them in the ground, I dont think my folks would appreciate me going and digging holes in the yard
I can cover them in newspapers and then put a tarp over that though.

Thought of some of the mountain Darlingtonia? They stand the cold really well.

I like the plan for overwintering Sarracenia as bare rhizomes in ZiplocŪ or other resealable bags, in the refrigerator.
They are safer, and it's easier to propagate them by rhizome division, from season to season.
