Anyone grow these? How much frost can they withstand? In particular, can the roots withstand freezing?
I've grown them before, but this was in a cactus greenhouse in Cornwall, where we got very little frost. In view of the last two winters, I don't want to risk losing my plants!

Pitcher Plants? They grow around here in the wild though we do get snow cover. I'm sure there are also different types but I am suspecting they can take some frost?

What sort of winter temperatures do you get? My main concern is how the roots would do in a frozen pot.

I'm in Canada Z. 4b which would mean something like -25C or lower but it would be a lot warmer under a layer of snow. If it was superficial freezing or if it were surrounded by mulch, I imagine they'd survive but again, don't know if there are different varieties?

There are several species, which may have different requirements.

Depends which species you are growing, some grown in Florida and others live with polar bears. If you don't know what you have post some pictures. All can take some frost. |

Flava, minor, leucophylla. It was down to -12 at times last winter, and I lost a lot of plants!
