How do I get my Passionflower (Passiflora incarnata a.k.a. Maypop) to set fruit?

Question

I bought some Passion Flower plants (Passiflora incarnata a.k.a. Maypop) and am hoping they will eventually set fruit. The seller told me they are self-fruiting, yet I'm not so sure. I would hate to wait until they bloom, just to find out they won't self-fertilize!

Does anybody know for sure if they are or are not self-fruiting? Is there a way I can find out (without waiting until it's too late)?

If they aren't self-fruiting, do I need to get the same type of plant for fertilization, or a different species of Passion Flower (which one?) Or does it not matter?

I'm not worried about pollination, plenty of bees and butterflies around! :)

Thanks!

Thanks Glenn, I know they grow wild in many areas, but definitely nowhere near me (NYC). So I just wonder whether you might actually have several plants growing near you, and it is being pollinated by them?

Answer 1

i have a pink passiflora (that sounds a little obscene, now i look at it), and it has fruited ever since it started flowering. and i haven't seen a single other one anywhere in my quadrant of the city. it fruits quite prolifically.

Answer 2

they are growing wild all over my yard with flowers and fruit on the same plant
