It appears that most passion flowers are tropical in nature, zones 9-11, but there are several that will grow in zone 6. It might be dicey to let them "winter-over", but you could get away with leaving them in Container Pots with something for them to cling to. Some varieties will drop their leaves in winter, but return in Spring . . . All appear to grow 10-40 feet.
Passion Flowers are some of the most generous vines around. With daily blooms over a long season . . .
