Here is a reference list of some of the hardy to half-hardy edible Passiflora hybrids and their pedigrees. Generally, I’m only including plants hardy to zone 8 or thereabouts, and only including cultivars that have incarnata, edulis, cincinnata, tucumanensis, or other edible and palatable Passiflora in their pedigree. I’ve made a few exceptions which will be bolded.
