OK, I give up, don't shoot me!!!!
What I meant was, if you visit Canada you can find people growing S.
flava outdoors and you can also find S. flava plants that have been
(illegally) planted into the wild. The temperatures in Canada are
generally a lot lower than most of western Europe where most of the
European CP experience is gained. If plants are hardy in Canada then I
would generally expect them to be reasonably hardy here in the UK and in
western Europe (e.g. Germany, Italy, France, UK).
However, Canadian winters are super dry, the snow squeaks when trodden
on. So plants from Canada can be very cold hardy but intolerant or less
tolerant of winter wet. I think this may be true to a certain extent
for Sarracenias. They look fine when frozen but awful when cold and
wet! S. purpurea seems very hardy though, no matter whether wet or dry.
Apologies for all this S flava distribution stuff. My next topic will
be "Plant Hunting the Wild populations of Heliamphora in Antartica".

Paul A number of people wrote to me about S. flava in Canada so I hope
this sets the record straight.
