Here is what the pergola looks like where the passion vine will run up one corner.

I do believe that there is a species of Passion Flower that is hardy to zone 7a with mulching. I may be wrong but I would look into it. I usually have the more tropical ones about, but this (droughty) year did not grow them.

P.S., Kiwi is one vigorous vine as you must recognize by now. I ripped mine out on the property fence but just got more of them for another location because I missed their..., exuberance for life! Are you sure they won'd just smother the passion vines?

From the photo those look like fuzzy kiwi's. No matter which type ONE kiwi vine can easily cover that structure. They are very vigorous growers. They need constant pruning to keep them in line. I grow them along with passionfruit vines, both the tropical P. edulis (purple fruited) and the native P. incarnata. Mine took a bit longer to fruit when grown in a pot but it will happen. My kiwi's never fruited in a pot. I grow my purple passionfruit in a 33 gallon tub with an extra large tomato cage. I train the vine to wrap around and around on it all winter in my greenhouse and then drag it over to my kitchen porch deck for the summer. It doesn't grow much during the hottest part of the year but can be very aggressive when things are cooler. It took a few years (maybe 4) for the passionfruit to make decent fruit when grown from seed. The natives also took a few years to get established (also grown from seed). Kiwi's were purchased as plants and even though they were large it took almost 7 years before I got a full sized crop off of them.

I can honestly say, I don't think I have ever seen a vine as smothering though luxuriant as a happy kiwi (Actinidia chinensis).

Charlie, you can plant Passion Flower outside.They will die back to the ground in the winter but will come back to flower and fruit next Summer.

My kiwi plants are Saanichton with a male Matua pollinator. Had blooms last spring, but the male blooms were killed by a late frost so the females did not get pollinated. Tropicalz7 I can't plant the passion fruit in the ground because the corner on which I want to run it is concrete.
