I think I once saw a small banana tree in a greenhouse on a school trip several years ago. It was maybe 3-4 meters high and produced these small 10cm bananas. That was just a project for fun I think, they mainly grew cucumber in that greenhouse. Outside, apple trees do ok. Cherry, pear and plums can be grown as well, but apple is pretty much the only one that does well enough to be grown commercially. Berries are better suited for our climate, those we have an overabundance of. If only someone would pick all of them, it's estimated that only 5% of the edible berries are harvested annually. Every Finn would need to pick about 350 pounds every year to get them all to use. The situation is the same for mushrooms as well.
