How do these do in pots? I have some 7 gal airpots I could put one or two in.
It’s getting controversial up in here I guess ?
They do fine in large pots, but freezing solid in the winter might not be good.
One of mine died in a 5 gallon, 0F winter temps
I deleted my post, I was going to say that I grew one Maypop by itself and it fruited the first year … but then I wasn’t sure if I had two seedlings right next to each other in the pot.
Maypop roots are not really that hardy, so pot culture can be risky. I found several years ago that the roots can take down to about 15F in a ~3 gallon pot raised off the ground before they die. Bigger pots that freeze more slowly may push that down a bit lower, but not much. The roots rarely get much below freezing underground even when the soil freezes. Much larger pots in contact with the ground, or even partially buried are much better for survival.

I’m growing many in large pots and plan on overwintering in insulated storage buildings that rarely freeze.

I got 16 seeds in a tray right now. 4 have come up. We wait and see. Excited to start my journey.
If you sell genesis seeds next year hit me up!

Yeah I would definitely bring them into the basement every winter. In fact they’d probably come inside once we start getting our first upper 20s like I do with the figs.

Interesting. I have read that the fruit ripening time for P. tucumanensis is much shorter (approx. 30 days compared to 90 days of P. incarnata) and that it does not require as hot weather (i.e. >25°C) as P. incarnata. Do you know how your hybrids have performed in conditions with colder summers? Though, of course, if they are not sigficantly hardier than P. incarnata itself whose root system tends to die if temperatures go below -25°C (as far as I have understood), that mostly matters for places like Scotland with warm winters and fairly cold summers.

I grew several P. tucumanensis many years ago. I only rarely got any fruit even with 7-8 distinct clones/seedlings and hand pollination. I never got any to cross with P. incarnata even with lots of wild vines and bees around me. The fruit ripened in about 45 days and my summer days were always quite warm, typically 30-35C during July and August. The hybrids with incarnata (aka “Intucus”) did not seem to mind the heat, but were much hardier than the parents. Foliage was hardy to at about -15C for the tucus and -12C for the hybrids (and about -2 to -3C for incarnata).
Even though the roots on the hybrids were very hardy, the tucus struggled a bit to re-emerge in late spring and took much of the summer to get re-established, so not really a longer term perennial. Any cooler and they would have to be protected so they didn’t die back to the ground in order to keep them going. My tucu and hybrid vines eventually all died off after I stopped covering them with a greenhouse.

When did genesis start producing ripe fruit this summer?

It ripened fruit earlier than expected, around Sept 10th-15th. It was in line with our Superior seedlings. So I think it may not actually be late ripening, but about average. Definitely not early.
