One of the best survival foods is called the “Jerusalem Artichoke.” It has the same caloric value as a potato and will grow like weeds in any soil and zone (but prefers colder zones.). They have more nutrition than potatoes as well. Downside is that if you dig them up, they will only last a few days. You can just keep them in the ground and harvest them on-demand. They are highly prolific and spread, so grow in a contained area is preferred. I just purchased some tubers and planted them in some grow bags. If the shit hits the fan, I plan on sectioning off half of my garden to grow them.

Interesting history as well. When Hitler invaded Europe, his troops stole most of the potatoes. France survived on Jerusalem Artichokes as the Germans didn’t know they were there.
