Passiflora caerulea can't take the winters;

I can't make up my mind about that. Mine shrugged off the last two
winters, despite the north wind blowing through its trellis. Other years
it has disappeared without trace during not very severe winters.
Fortunately it tends to self seed everywhere so I always have replacements.
IME it makes no attempt to climb above whatever's supporting it so it's
a relatively well behaved climber.
