Wow that's great. I hope there are good seeds in it. Are they self fertile or do they need a pollinator?

I figured I would not have fruit on it as I have no other Tacsonias or Tacsonia Hybrids in my yard. The pollination could be two things: self or there is a large Vitifolia flowering next to it, which could be the possible pollinator. I guess I thought Tacsonias do not usually self and don't often mix with other types of passionflowers. I hope the fruit continues to grow and has some viable seeds. I know you and many others are pretty knowledgable, what are the usual characteristics of Tacsonias?

Update a few weeks later

2 more Oaklandia fruit

I havent grown the Tacsonias so I am not familiar with what pollinates them. Several varieties of passies do need a pollinator and some dont. Caerulea will pollinate just about anything in my yard lol. I have pollinated many varieties with Vitifolia as well so it may very well be your pollinator. Your Tacsonia is looking very nice. Hope u can get some seeds and maybe some of tge babies will look like Tacsonias and also be hardy lol

I think I have heard that Oaklandia does not produce pollen, and fruit seems to be uncommon, so probably not selfing. The vitifolia may be pollinating your Oaklandia, but I'm thinking the most likely source is wild P. incarnata pollen brought in by bees. That would be a nice cross. Please let us know when these ripen and also how they taste. Tacsonias usually have very good tasting fruit.

Still growing. I think it is the vitifolia pollinating 'Oaklandia.' Hard to know if there will be seeds. I saw a hummingbird enthusiastically visiting the vitifolia. My variety of Incarnata has not bloomed yet, but it is a great pollinator that is also a good possibility.

They are doing good ! I get seeds on most of my passies except for Belotii. That one made big fat fruits but when I opened them they were hollow lol. I have no clue what pollinated them or if that made a difference.

I think this one is ripening. It is getting a little yellow on the bottom.

That's great I will keep my fingers crossed for you for fertile seeds.

I'd love an update if possible... Pretty please. Were there seeds? Did you try to germinate them? If so, what came of it all?

There have been a few tacsonia x passiflora hybrids recently, including my WKV hybrids, it seems some tacsonia x tacsonia hybrids are then more easily then crossed with the Passiflora section species. Oaklandia would fall into this, you should be able to guess the pollen donor if an when any seedlings flower. The WKV fruit also had over 100 viable seeds each.

Thank you!

I have only two types of Passiflora. The oaklandia and a loefgrenii (Garlic Passionfruit). I have had many fruits on both. I very recently, and for the first time, harvested some from the loefgrenii. I will be watching the oaklandia very closely and harvested the next one I find. Do you think there's a possibility that they will germinate into something?

I did not get any of the seeds to germinate. Loefgrenii is quite the pollinator. You might have success with that match.

Nice! Thank you for taking the time to reply. Do you know of any other way to propagate the oaklandia? I've tried layering many times and it just never takes.

The way I get it to propagate it is to get plant a cutting then get a clear plastic bag and cut a tiny hole at the top. Cover the pot and plant, like making a mini green house. Water your cutting and leave it under the plastic for 2 to 2 and a half weeks. It requires a large amount of humidity. I get almost every cutting to grow this way.

Thank you very much! I will certainly try that. Should I also put it on a heating mat?

Might not hurt, heating mat. I live in Florida so everyday is nearly a heating mat. I use regular gallon size zip lock bags and put a small bamboo stick in the pot just to hold the bag up. After I see new growth I leave the cuttings under the bag and then when the new growth appears as if it is growing I will remove the plastic. If the new growth wilts I will put it back under the bag for longer.

LCOP I saw your hybrids, absolutely beautiful. Do you plan to market any of your plants?

A couple have found their way into the US, so should be around sometime. Passiflora Debbie Hescott has flowered in California, and has coped in southern England in a unheated greenhouse, so Florida is probably ok too.

I Hope that the tacsonia x passiflora hybrids WKV x various, that cope at 34 oC and down to -1.9 oC will also be tested in florida and the USA.

We have about 150 species and hybrids growing in our greenhouses so always have a good selection in flower to cross most days. There is a nice WKV x aff pallens hybrid that hopefully will be made available next year, its a sibling to the one posted on my webpages, but not at this moment in our collection, and a lovely flower.

There was a good article in the first issue of POJ [passiflora online journal] on the propagation of P. parritae, so probably also goes for the difficult parritae hybrids too.

Passiflora Online Journal

Very useful article. Thank you!

Oaklandia is definitely not a P. parritae hybrid. Possibly tarminiata x manicata, but no one knows for sure. Unfortunately, it has never produced viable seeds as far as I know. I checked about 30 open pollinated seeds from Oaklandia that had many tacsonias as possible parents, and not a single one had any viable contents. Mine is extremely heat tolerant, but has not bloomed in two years.

its listed on a few websites as parritae x tarminiana, and on others as tarminiana x manicata, We dont have it here so cant see its properties. Hybrids should not be allowed to be registered without the parents, so there is no doubt of the linage. I always register both parents for my hybrids. P. Debbie Hescott is P. Jayne T x citrina for example, and P. Jayne T is capsularis x conzattiana. with both citrina and conzattiana in it Debbie Hescott is in the Group 2 part of xerogona [see below] and is [P. capsularis x P. conzattiana] x P. citrina so only a 3 species hybrid not the 4 or 5 species hybrids we are now creating.

Analysis of the direction of crosses
suggests:
Group 1. capsularis, rubra &
sanguinolenta
Group 2. citrina, cobanensis &
conzattiana
Group 3. quinquangularis
Group 4. rovirosae

Group 2 xerogonas seem to only produce fruit with another Group 2 species/hybrid or another different plant of its own species. Group 1 species seem to be more compatable with the other groups, but will not pollinate a group 2 easily.

I will have to keep this information bookmarked. If I were guessing on the parents of 'Oaklandia,' I would say P. manicata.
