I'm getting flowers on my P. laurifolia (Jamaican passionfruit) for the first time, and am wondering what other Passifloras are compatible for pollination. I have another genetically distinct vine of it, but it's not flowering right now. (This is the first time it's flowered in about 6 years.)
I remember reading somewhere, but I can't find it, that it is compatible with other species, but I can't find the reference. Anyone know? I think I will be able to get pollen from P. alata, P. edulis, and maybe some varieties of P. caerulea.
