“Id like to have something I could grow that would just be like a weed - grow like crazy with no tending, until SHTF. LOL”
Unfortunately tobacco ain’t it! :-D
If you could come up with a use for morning glory or kudzu you could buy your private redoubt and stockpile everything!
Git them brain cells to working.
Maybe I’ll just concentrate on dandy lions. I hear they make a terrific wine. LOL
Kudzu is actually edible, although there’s not much sellable you can do with it. But the vine tips, leaves, and flowers are all perfectly safe and reasonably tasty, and the roots are edible and darn good for you if you dry and grind them. I want to try my hand at kudzu jelly this year, and see if it tastes as good as the flowers smell.
