Dear All,

I have a passion fruit vine that is about a year old. It is flowering superfluously but the flowers keep falling off.

They appear to be cut at the base of the flower leaving the empty sepal on the vine. All the flowers that fall off seem to be pollinated as i can see a small developing ovary / fruit.
There are a lot of ants all over the vine. Are they the cause? Please see pics to know what I'm talking about

I don't think they have been pollinated.

Looks normal to me. Passion vines typically produce few fruit.

Ants are actually encouraged to visit by the vine (nectaries) and not a problem.

Here's a neat blog post on passion flower.

I have one fruit on my large plant. Will it make seeds?

That's what fruits are: seed pods. Some seed pods are just more edible than others.

Hi fufuknox
I'm enchanted with Passiflora, and grew 5 vines this year.
I noticed most blooms dropped from the vine after fully opening and displaying for three days. Of all the flowers, only 4 pollinated and produced fruit, and those were on the 'Blue-Eyed Susan' vine.
Of course, you and I are probably on the opposite ends of the climate zone, so I did not have any expectations of fruit.

Here are some Passiflora pix. The first picture was intened to show the globe spider tending the passies, but you see the fruit. The last picture shows the 100 foot trellis (left side of picture) I made for the vines. Some passi vines needed all that space and some were very dainty, and didn't. None of the fruit matured because we have such a short season.

my passion fruit flowers just become yellowish and fall off. what could be the cause?
