In a mild winter, which has been common here of late, Passiflora caerulea is evergreen. It will die to the ground in a cold winter and is late to come up in the spring. Can be invasive. Will send up new shoots at a fair distance from the original plant.

I definitely agree with it being invasive; constantly pulling them up many distances away from original plant. It has grown into a massive plant covered with loads of blooms.
