Some hardy grapevine? Perennial preferred.
Whatever you get make sure it is ‘self fertile’ meaning that you don’t need another plant nearby to provide pollen and allow for fruit.
Potato’s, easy to grow and high carb.
Its very protected. Almost anything would do. I suppose you are in the northern hemisphere? If so, great sunlight abd greenhouse effect. You could do passionfruit for example
Stockholm so, freezing winters. And these days insane tropic summers apparently.
Passion fruit eeeey? That sounds lovely, I’ll check out if there are kinds that can withstand temperatures of ~-15C
Haha. -15c no chance of passion fruit. But I suppose -15C is the temp outside. What is the minimum temp inside that space?
;)
I haven’t measured it before. Guessing around -10,-7C somewhere due to residual heat from our living room and the glasseed balcony being wind resistant.
Apple tree, pear, cherry are all cold resistant but obviously unfit for a grow bag on the balcony. I’ve heard there are are types of grapvine that can do swell in hardiness zone 5ish, not sure which kind yet conflicting info on the webz.
Where I used to live there are some grapevines that give big round passionfruit tasting grapes that resist at least -5°C
