Yellow Passion Fruit Is Self Sterile And Needs A Second Vine, Does The Second Vine Need To Be The Same Variety Of Passion Fruit?

Question

I have a passiflora ligularis and a Passiflora edulis flavicarpa that are young plants and will probably be 1-2 years before fruiting. My question is if these are compatable to help the self sterile issue that the yellow passion fruit have, or do I need to have 2 ligularis and 2 flavicarpa in order to get fruit??? We have a greenhouse that they are growing in. Thank you!

Answer 1

It needs two vines of different parentage so you should be good. Here is more:
