Depending on where you are sweet potatoes are often grown as an ornamental vine but the tubers are literally what you eat. You can grow them in the ground or in pots (I recommend pots so it’s easier to harvest, ymmv). Tomatos, blueberries, herbs, sunflowers, and strawberries are probably pretty easy to get away with too as long as you keep them organized looking.
If you don’t have an HOA and you live in its native range, central north america, the sunchoke is a crazy good source of food. Honestly too crazy, once you start growing it, it’ll be there forever and it’ll try to take over everything, but you’ll have the food there buried waiting for you year round. You can also grow it in pots, just be careful with the tubers and the soil, they will seriously spread out of control.
I just finished watching the series for the first time the other day. I started out a little skeptical it would have aged well and there’s a few moments that reminded me it came out in the early 90s, but wow what a fantastic show. And what a time to be watching it, some of those newscast episodes hit close to home.
I think it’ll be on my rewatch list too now.
