I have a post titled "Maypop Bloom," your flower seems very similar to my P. incarnata. If you have multiplication of your original plant, it is likely a P. incarnata. I noticed my edulis in it's juvenile form looks almost shrubby with single lobed leaves, as my edulis matures it develops additional lobes on the leaves and sends out tendrils.

I remember you had a post earlier about pollination and fruit production. I have found that a P. incarnata x P. Vitifolia cross works. Both fruits of each plant are supposed to taste good. Right now I have 3 fruits on my P. incarnata and 1 on my P. vitifolia from this particular cross. They bloom at similar times, so it's easier to obtain fresh pollen.

yes, the large plant i have, which i think is from last year (maypop i think)
has lots of flowers. sometimes 2-3 daily.
no fruit.
tried using a different maypop, and also a caerulea as pollinators.

i have one in a container
(the pic with the bee)
and that plant just gave me fruit.
not ready to eat yet, but this is a small young plant.

starting to think none of these are edulis.
