Quite a long time ago, I ordered seeds (from chileflora, no idea how respectable they are) of "Passiflora tripartita". I was a bit of a dilettante with passifloras then and only two sprouted and just one survived until now.
Anyway, I now have a beautiful passiflora that survives Belgian winters (in the city, and in a pot that I could always bring inside if it was too cold) but none of the flowers ever set fruit, even with an apparently sufficient supply of bees, and with my attempted manual pollination.
From what I can read, most sources (like
https://www.cabi.org/isc/datasheet/38802) seem to say that Passiflora tripartita
var. molissima can self-pollinate (though it can likely not be pollinated by the Passiflora cerulea that are common around me in the city) so having just one should not be a problem.
Now, that leads me to my question: my seeds were just labelled as "Passiflora tripartita", no variety mentioned. The webshop is still here after How do I know if it's var. molissima (which seems by far the most common) or not?
Here's a picture I took of a flower last year when it really started taking off:
I have another question, I'd like to share it with my dad who lives in Western France where it should grow just fine, but I have never, not once, managed to root any cutting from it. Unlike my other passifloras, this one seems to be very recalcitrant, and it doesn't make any shoots from its roots either. Any suggestions? They also aren't graft compatible (or not very) with P. cerulea so that's not an option either.
