So should be pretty hardy?

No. Constance Elliott is, but is less hardy than the blue form.
Amethyst isn't, and is a less hardy hybrid. Purple Rain, I don't
know about.

Amythyst is less hardy? Its listed as down to -8C.. That is one of
the ones I managed to find information on..

ANyway.. Thanks.. I will take cuttings as backup and see what I can get
away with.. We are quite sheltered here in London anyway..

Beware temp listings for passiflora, only P. caerulea is remotely hardy in
the UK "all the time" P. Amethyst is likely to survive -1 and then only if
not too wet. P. Purple haze and Purple Rain are both caerulea X Amethyst,
and are a bit hardier. P. incarnata hybrids are often sold as hardy but
dislike winter wet (used to the ground freezing in winter) Cuttings are
always a good idea!!
