I believe there are bananas that will grow outdoors in zone 8 if you cut them back and cover them in winter. I’m pretty sure I’ve read about people doing this.
You can get good fruit from plants in pots with Citrus, pomegrenade, carissa, macadamia, hapnophyllum, tamarillo etc. If you have a heated greenhouse edible bananas, papayas, cocoa, soursop etc grow well, too. Mango and avocado trees grow well in greenhouses but i have never seen them set fruit there. People say its possible, though.
ok, you convinced me that its possible in Texas and Japan. Still not sure it can work in Germany or other zone 8b locations. Maybe light, pollinators or other issues. But i wish it would be possible. guess the mangoes from here would be very bland, though.
I am in zone 6 and i build a geodesic dome greenhouse with double walls( means insulated ) .My goal its to grow a few cherimoya trees ,somme sugar apples( i like theyr fast fruiting) and uvaria grandiflora .These are valuable fruits and verry rare to find to buy where i am.Mangos and avocados are cheap and can be found at any supermarket so i wont try growing them.The heating will be made with a rocket stove on wood but probably il only use that just a few weeks a year.

I use a 100K BTU propane heater with a free standing construction heater as backup. I have natural gas pipe there but il make the rocket stove on wood because i have branches and wood that its free.About polination ,i am a beekeper but cant use the beehives for it ,especially in winter.Instead il use bumblebees in the greenhouse that i catch and rear myself from the wild.Your greenhouse its verry nice,has a clasic design and the sliding window its nice too even thogh if reminds me of Hitlers window.

Bees, honey and bumble, are just a small part of my pollinators. I have moths, butterflies, wasps, and several species of flies. This Gwen avocado was covered in flies.
