Your best bet is P. 'Incense', which should be hardy and fragrant. However, it will need a pollinator to set fruit, and even then will likely be very shy bearing, even with hand-pollination. P. incarnata would be your best (only?) choice for a pollinator. Two different incarnatas would give you lots of fruit (on the incarnatas). The fragrance may be a bit of a gamble, as incarnata can smell good or bad (and some fruits are much better/worse than others). Probably nothing else exists that would be reliably hardy in your zone, that meets your criteria.

ya I don't know.. It gets arctic there, from what I know of living Up-state & watching ... That show with "lenny" and "brisco" and those guys- the cop one? yeah.

Maybe a hardy kiwi for the fruit, and caerulia or something for the flowers. But yeah I don't think you're going to have much luck with the "arctic edible passionflower" search.

Could try Blue Crown-pretty darn hardy and I've used it to pollinate Incense with a couple of successes. Although you're right Kiwinut for as many as I've tried to pollinate, I've had more fail than succeed. Not sure if maybe it's a time of day thing or what.

I had 3 Blue Crowns survive last year's horrific winter in the Hi Desert of So Calif (zone 8 - sunset 11) 1 of them was on the front porch, did not lose it's leaves. The other 2 were in pots out in all of the rain, 3x normal amount, some snow, 15-25F weather for about a week.

Only problem with Blue Crown is the fruit may not be particularly tasty, but you can use it to pollinate, it's hardy and is fragrant, at least mine are.

Thanks for the suggestions! We're not that cold here in the city. About teens-20s in the winters max. :-) Upstate NY is a different thing. I suppose, I will go with the P. incense, and look for fruit elsewhere. I am more into the fragrant colorful flowers. And I might take the suggestion to plant incarnata or blue crown (is that the same as caerulea?) as pollinators. I do nothave much space for a Kiwi (no arbor).
