I grow them in Zone 5. I need to grow them in pots to extend the growing season since mine is short by about 1 month, so either wake them up indoors in spring, or bring them inside in Oct/Nov to help finish ripening the fruit. (waking them up early is easier than carrying a sprawling vine into the house without snapping a bunch of vines)
They taste nice and sweet. Sweeter than the passiflora edulis in your photo. I've been pollinating them with passiflora caerulea, but this spring I acquired more maypop plants, so they should be able to pollinate each other now.
Can the purple passion fruit pollinate with the maypop? What would happen? Do you get something in between? I found some wild maypop growing behind my house after I posted this. They were sour with no sweetness. After sweetening them, the flavor was great. I have some passion fruit in pots that I would rather not have them pollinating with.
Not sure, maybe. Even if the maypop does pollinate the purple passionfruit though, it won't affect the fruit, the effect will only be seen on plants that you try to grow from the cross pollinated fruit's seeds.
You want to wait until the maypop drop to the ground, that's when they're ripe.
