If you have two distinct seedlings, they will pollinate one another. All paasifloras are that way. Only if you have genetic clones will you not be able to fruit them if they are not fertile.

I have only grown one maypop clone.
It was from a single seed I started ~ 10 years ago.
The vine has fruited prolifically for me and for those who have recieved cuttings from me.
So at least some May Pops are self fertile.
Unfortunately the fruit taste like a combination of Bananna, Pineapple, and dirty socks.

Caution, May-pop, P. incarnata is root invasive
Caution, May-pop, P. incarnata is root invasive.
It will send up new plant all along its root system. Also can send roots under concrete 50 or more feet, to come up where you never thought they could.

David is correct
Maypop is very invasive, but it is a preaty weed.
I would only advise planting it in an area that you dont mind it naturalizing.

I don't mind it being invasive. In my area it will die to the ground every winter anyway. I am a little concerned about the dirty socks description though. Anyone else have opinions on the taste?

Maypop maybe edible but not good to eat, I thought Jeff in Woodland was being generous with his description.

Actually P. incarnata dies to the ground as it is deciduous in the winter. The fleshy roots survive in Connecticut and Massachusetts. They can survive down to -2 degrees F. Then in the spring the plant appears all over, far from its original planting. Roundup only kills nearby plants. This one is best planted in a pot to contain it. P. caerula is tame by comparison. P. Incense is a hybrid of P. incarnata and P. cincinnata that is beautiful and fragrant and well worth growing. It too will survive down to 16 degrees F and suckers, but is worth it. Here in Nipomo it too is deciduous. Nice thing is you can dig up a sucker to propagate it. Never have seen a fruit, but supposedly it has a 2 inch fruit that is sweet and a rose-like aroma. The flowers are self sterile and produce no pollen, so maybe I need to work on that. I used to hybridize Passiflora using P. caerula pollen and created some interesting "monsters". P. quadrangularis flowers are known for large size, but P. Incense flowers are larger (5-51/2 inches). Absolutely my favoritre passion flower!

More on P. incarnata
My biggest problem is nematodes, it only lasts a couple years, 3 at most. But a friend near me, in more sandier soil and colder in winter, his seems to not be troubled with the Nematodes.
Anyway the main reason to grow P. incarnata is medicinal, the leaves are a highly effective nervine herb, with many neurological benefits to help nerves and muscles to relax, induce sleep, mild pain killer and etc. I use it and skullcap twice daily. Helps me to remain less stressed during the day, and before bed helps me to relax, so I can sleep, and go to sleep far more quickly.
To restrict the roots, just retain the roots as if you were growing bamboo.

David, I'm surprised you have a nematode problem with your mulching. My pumpkins always have world-class nematode nodules at the end of the season, but I put lots of mulch in and on top of the planting hole for passiflora and it stopped being a problem. Our soil is pure dune sand for 300 ft,. down.

Jack, It is our Summer heat, and warmer soils.
It is our Summer heat, and warmer soils. And the P. incarnata has been in my back yard, southwest exposure, very hot there. It should be better as some palms and trees grow taller to cause some more shading to cool the soil. But my yard in air flow restricted area often gets 8 to 10 degrees hotter. The warmer the soil is, the worse the nematodes can be, especially with the no mulch or not much organic material in the soil.
I got ride of my Perlette ? grapes, they were turning to raisins in June and July before even ripe enough to eat. I dumped them and also moved my the keeper grapes to a area where they are shaded for part of the day, they do much better.
