Anyone have experience growing Passiflora quadrangularis also known as Giant Granadilla? The photos are of the one we have and it’s fruit, but we have struggled to get very large, full fruit. Do you need to hand pollinate them? Or is our fruit size simply a cultivar issue?
Where are you located? In West Africa they grow and pollinate without manual intervention. I’ve had some that are about 2kgs and the seed/juice quantity about 300mL in one fruit if I had to guess.
These are in Florida grown in 15 gallon pots (in zone C to be specific for you)
We grow them in Malawi. Hand pollination is not usually necessary although when the plant is young we experience quite a bit of blossom drop. As it matures, this gets better. We have large fruits probably around 2kg+.
