My passion flower vine is quite prolific in producing flowers, however they
never set fruit.

It's about 3 years old, & is quite full. I had a vine with identical
flowers in the past that produced bountiful fruit. There is no indication
of any fruit growing after the flowering ( such as beginning to grow, then
dropping).

Oddly, my Valencia orange tree, about 50' away & in a lower garden flowered,
then did not set fruit. Several other fruit trees are doing just dandy.

Any ideas?

Thanks much!

I've read that SOME passion flowers simply will not produce fruit without
cross-pollinating with another vine from a separate cloned strain, but
that this trait varies from strain to strain, some being fully
self-fertile. Passiflora hahnii invariably requires an unrelated clone to
pollinate it, & P. murucuja is very curiously induced to self-pollinate
only when an unrelated clone attempts to pollinate it. The two species
that are most apt to self-pollinate are P. incarnata & the most commonly
grown P. caerulea, but it is never a sure thing & a for some strains a
different clone may be needed.
