Maypops

[walt]

Yes.  Like I need more work.
Some years back I bought 2 Passiflora incarnata, maypops, from Loggees.  One was the regular blueish, the other was white.  The white didn't do well and soon died.  The blueish died later, after a couple years.  Lack of water during vacation?
So 2 years ago, a friend bought a house a couple of blocks away.  He was removing ornamental plants to save work and leave more time and space to play with his kids.  Along with lilies, peonies, roses, and who knows what else that my wife brought home, there were maypop vines.  These maypops took off and made themselves at home.  They made no fruit, so I assumed they were all one seedling.  They certainly do spread.  They had grown under a 4 foot wide cement sidewalk and come out the other side.  So they could have been all one seedling.  But yesterday, this being after 4 years of so, and several divisions where I think I only moved a piece of one plant, I saw a couple of fruit.  Closer looking showed me a total of 5 fruit, all close together on a big mess of vines.  The rest of the mess of vines had no fruit, though there had been flowers all over it.  The fruit look about 1/2 grown.

While writing the above, it occurred to me that while I am outside the known range of maypops, I have seen then wild along the Walnut River 150 miles southeast of here,  They just might be wild along the Saline River about 1 mile from here.  An insect or hummingbird might have pollinated it.  I hadn't thought of that.

So anyway, I have been on the facebook passiflora group, mainly to admire the pictures.  There are hybrids of many species, including P. incarnata with tropicals.  Some are second generation hybrids.  I wonder about asking them for pollen from those hybrids, to get more variation into the hardy passifloras.  Not that I need more work.

For the last month or more, my maypop has had several blooms a day.  Today zero.  I thought they bloomed until frost.  I never noticed them quitting before frost, but maybe they did and I wasn't paying attention.  Anyone know?

Sorry I can`t tell. But I have the first flowers on a caerulea outside in the garden this year. Strangely there are only 4 or 5 buds. The twig is growing further and is 1 meter long behind the buds. But it stopped making buds after that.
That is similiar to your observation.
An incarnata in the greenhouse is still making new buds. Maybe it could depend on the temperature?

[walt]

They stopped blooming a few days before the temperature dropped.  Or maybe there were 2 drops.  One from damn hot to mildly hot. The second from mildly hot to cool.

Here's an "incense" incarnata hybrid that's said to be hardy. I have a plant that's fairly small that I will bring inside soon for the winter.

Thanks.  I wonder if it is fertile.

So here's some information on 'Incense' passiflora.
It is an F1 hybrid between Passiflora incarnata x cincinnata. Actually, I've seen it listed as Passiflora incarnata x a different passiflora sp. that also starts with c.
But anyway, 'Incense' is pollen sterile, but sets fruit when pollinated by P. incarnata.
So on facebook, on the Hardy Passiflora group, it was discussed, and Paderic offered me some seeds of Passiflora incarnata and of Incense OP, which is likely Incense x Pincarnata. So the seeds arrived and today I started soaking them. I'm told to soak for 24 hours then plant them. Will do.

If you cut off a little bit of the seed on one edge (only that the seed coat is open) germination is much faster. I tried soaking too but germination is very slow to none for me.
This winter I lost all my incarnata plants in the greenhouse. Mice love incarnata roots
Now I have an incarnata hybrid called "Petra" in the garden. It is setting flowers now. I am curious if it will be hardy enough.

[walt]

Thanks for the germination tip.  I have enough seeds I can try both ways.

[walt]

I now have over 20 seedlings of maypops, P. incarnata, and hybrids that are 3/4 P. incarnata. Dang. I'm sitting here in the city library and I can't remember the hybrid name that was the seed parent of some of the seeds. It was pollen sterile, so the father was incarnata, as was one of its other grandfathers.
Seeds came from Padric on facebook.

I don't know if they should be planted in the ground or try to overwinter them in pots inside. I doubt they would get big enough to survive outside this winter.

[walt]

My maypops have no more flower buds.  There will be no fruit or seeds this year.  
However, I do have seedlings from seeds from Padric on Cold Hardy Passifloras on facebook.
I think the seedlings are too small to make it through the winter outside.  I'll have to make room in my greenhouse that isn't built yet.  I see a potential problem here.

The woman here bought two little tiny vines this past spring, pathetic little things but I took charge of them and one lived and has grown quite large but no flowers. I know it's possible they can overwinter here cause there used to be some that grew up the porch and along the sidewalk at my brother's old house. My previous attempts to get them established here failed but this is the biggest best vine I'v had so far. Sure hope it lives.

If it does will it need another vine to pollinate?
