I have a question for both you Plantinyum and Kevin.
Did you ever get a fruit to set on your passion fruit flower?
I have one that I don't know what variety is it. I bought a small plant thinking it was Lilikoi but after I posted my flower photos I was informed that I have a Passiflora Decaisneana.
Here's a photo of my flower on my vine. I also have another 4 flowers that will open in a week (11/27/21). The first flower shown in this photo was hand pollinated but it did not hold, if fell off with no fruit set.
hi, no i did not get any fruit set on mine the past year ,back then it only had like 2-3 flowers.
This year i planted it in my gh in the ground and it exploded with growth trought summer, it started blooming around september just as the temps started to cool down.
It had i would guess around 40 flowers this year ,as one might expect i self pollinated them as best as i could yet it did not set any fruit this year also.
One observation i had was that the first blooms were the biggest and most colourfull ,as the blooming period was rollin the blooms were getting smaller and paler, like the one in your pic. Seems the species is a fall bloomer in my region so it does not help itself setting fruit , since it misses the optimal conditions for the purpose.
In one tread people suggested to cross it with caerulea pollen ,i was going to do that but instead got my caerulea plants severely neglected and did not had a single bloom this year. If u have one flowering now, i suggest u to try to cross them.
