I bought multiple specimens of P. edulis 'McCain' from Logee's in early 2014. I kept one in a large pot, and the others were planted in-ground. The potted specimen was the only one that ever flowered the entire summer. (Of course, this was also observed with P. edulis 'Possum Purple.') It started flowering in July, and it does set fruit easily compared to other P. edulis / P. flavicarpa, but it is NOT entirely self-fertile, as some people claim it to be. I never fully isolated my pollination attempts, but it became obvious quite quickly that fruit developed more often with cross-pollination. (I often used P. incarnata only because it was available to me every day of the season.) The first fruit matured in September. Most of the fruit developed brown spots and seemed to have started to rot. I was never able to harvest a single fruit that did not taste rancid, although that probably had something to do with care of the plant or disease. I lost my only potted specimen in early 2015 due to mealybugs that spread from another plant indoors. I do highly recommend this passion flower vine (over P. 'Possum Purple'), but you may need to cross-pollinate to get the most fruit, and if you do not live in a tropical region, you'll need to find some way to keep the plant in bright light indoors for the winter. To treat spider mites and mealybugs, try using neem oil. ... I am eager to replace my 'McCain' when it becomes available through Logee's again!
