Wow that is impressive! I’d gladly take a wandering root cutting from you if you are offering. 
Do you save seeds? It might be less effort to distribute seeds rather than digging roots and could solve the fruit set issue if the seedlings will cross pollinate each other

sorry, just saw this…
No, AFAIK lutea and incarnata won’t cross pollenate. Lutea would more likely cross with other bat leaved passiflora (like citrina and capsularis).
I have a few different incarnata and more than a half-dozen other varieties.
I checked on the three Passiflora edulis plants I grew from seed last year and decided to leave them outside this winter. They basically burst at the base and turned into ice.

I started some seeds from Prairie Moon Nursery this spring. Got a couple seedlings in pots I’m over-wintering to plant next spring. Prairie Moon claims for their seed source they started and grew quite a few vines at the home location in zone 4 of Minnesota. Out of those vines, they had two survive their winters and fruit. If that’s the case, hardiness shouldn’t be a problem at all for me. Whether they’ll have enough heat units to mature fruit I doubt, but at least there will be pretty flowers.
My Panama red isn’t doing too hot in the greenhouse but i think it was because i didn’t visit them for about a week and so… no watering… 
i feel bad but the giant probably red rover and my hybrid from seed is doing great. Never showed signs of water stress so i figured they’d all be good. Little did i know… could be the weather too.
Maypop can do lots of odd things like randomly changing leaf lobe numbers, flowers on the end of tendrils, etc but this ribbon-like “fused” stem is a new one

I’ve seen that mutation on a few weeds here and there, I think like lambsquarter and Lactuca or something similar, it might be related to fasciation

Very cool! Have you noticed it doing anything different with flowers or fruit as a result of this mutation?

Hi!
To be honest I totally forgot about this and haven’t kept an eye on it. I will check today. Thanks for the reminder!
Meanwhile I’ve had a bumper crop of fruit this year. Recently juiced a bunch and boy oh boy I LOVE the juice!
We’re also gonna make a syrup/reduction to drizzle over cheesecake, ice cream etc. it’s so great.

Maypops are coming! This was planted in 2023 and is now LOADED with maypops
I got two vines from logees and only 1 survived. I’m surprised it has so much fruit since I thought they weren’t self fruitful. They still need some more time before I open them and check the flavor

My incarnata vine dropped his first and only fruit, the only one that accepted the self pollination.
Not very large, light green skin, to my surprise aromatic and sweet but not sour, not a lot of juice though. Is that normal? I mean the lack of sourness and the lack of juice dripping compared to a regular passion fruit?

How old is your vine? Are there any other incarnata nearby?
In my experience incarnata is less flavorful and juicy overall than “grocery store” passion fruit species.

It’s 2 years old. Growing near a Fata Confetto hybrid, but the incarnata seems incompatible to receive the hybrid pollen. No others nearby because it’s not very popular here in Italy

Yes - the interior of incarnata is quite different. The seeds are in well contained arils versus a “soup” like in tropical species.
So yes you won’t get juice dripping unless you mash the fruit or cut some arils with a knife.
Some incarnata vines can have fruit with very dry arils while others have large plump juicy arils.

Thanks for the clarification, next spring I’ll plant some selected incarnata from Lubera (swiss nursery), maybe the cross pollination will improve the overall quality of the fruit.

Update: I reached out about import requirements for passiflora incarnata. Unfortunately it is on the quarantine list SO if we do pursue importing live seedlings it will need to be quarantined for 2 years.
Maybe this is still worth it for those who are more passionate.
However, seeds can be imported as normal

Passiflora seed are pretty easy to germinate so I don’t think this is too much of a roadblock.

I have the ‘Eia Popeia’ cultivar from Lubera and so far my attempts at cross-pollination with ‘Fata Confetto’ have also all failed in both directions. Hopefully you can get some good results with your other incarnata.
