Supposedly all Sarracenia species have been grown outdoors
successfully in Zone 5B (Michigan and New England) even though most of
them are from the Gulf or southern Atlantic coasts. S. purpurea is by
far the hardiest (native up to Zones 1 or 2), but isn't very tall
except in flower. S. flava is presumably the next hardiest based on
range. I've not yet tried them myself, but it sounds like some
important hardiness factors might be making your bog deep enough that
it doesn't freeze to the bottom and getting good growth of live
sphagnum over the surface to protect the other plants.
