They are fairly tough, but won't survive their roots freezing. They
DEFINITELY need good drainage. Is it really an absolute that you can't
plant them?

I have a P. incarnata - which grows up to Canada, but is VERY delicate
in the UK - by growing it in the rain shadow of the eaves. It is a
herbaceous species.
