I can grow fruiting types in Zone 7 Washington DC. There are lots of passion fruits types out there.

Hmm, my maypop died to the ground in Richmond, VA. I’m surprised that any of the more tropical versions would survive a winter at all.
My maypop has yet to resprout in z5 here, I have hopes for her and she stayed in snow cover for the winter but its just time for blackberries to pop up so i hope it just takes a while as last year was the year i planted it and it didnt come up until end of may or june sometime.
Passion fruit vine doesn’t last forever, five to seven years is a long life for a passionfruit vine accord to this article
My first Frederick vine lasted about that long. It grew over a 50 ft overhead trellis and onto the adjacent grape trellis and other trees. On the best years I had passion fruits hanging everywhere and they tasted very nice. My family and relatives loved them in simple passion fruit drink. I think the rind is too bitter for the squirrels so I have never seen more than one half-eaten fruit each time. One day the vine simply died. The branches dried up including the unripened fruits. I have two more growing on two different trellises now because my sisters like the fruits but they don’t have the space to grow. Please note that the ants like the flowers so don’t plant next to the house. I don’t spray anything but the ants on the passion fruit vine don’t bother me as much as the ants on the raspberry plants, which I am thinking about removing because of that reason. I don’t see any ants on blackberry plants, both with thorn or thornless varieties, so that may be a better choice.
No Maypop sold here. We have 2 kinds of flowering passion vines, but non fruiting. I bought a white flowering vine. No buds yet, but it will bloom all summer, and not totally die back in winter. I would love a passionfruit to grow! Somebody invent one!
Mine finally started growing in early May. It’s flowering now, but only maybe 1-1.5 feet high.
I have a passionfruit vine on a 8’ long 4-wire trellis. It’s completely overgrown the trellis and is starting to trail down the far post. I’ve planted a grape vine on the far side and it’s slowly making its way up the post. This coming winter I’ll have to prune away the passionfruit from two of the wires and let the grape have those two. I figure it’ll be a constant battle to keep the passionfruit from smothering the grape vine. I’m rooting a couple more grape varieties, so I’ll have to put up another trellis on the other side of the yard.
In the meantime I’m growing another PF variety on the fence. It’s been a constant battle to keep the stupid snails off the vine as they really seem to like them.
