From this online video. The WWII Crops That Outsmarted Famine
https://youtu.be/EVIb2kUZLRk?si=sqnWoyK9zJlPXpfc
there is a list of plants that they propose were the mainstay plants for Victory Gardens. The list covers both northern United States and southern United States. The primary criteria were these plants could be grown in smaller plots as you would expect households in the 1940's to have. Additionally, the nutrition density, days to harvest, as well as climate and disease tolerances.
I recommend watching the video for more details on each.
Here is the list, not in the order shown in the video:
Di Chicco Broccoli
Charleston Grey Watermelon
Red Romaine Lettuce
Golden Wax Beans
Kusah Squash
Swiss Chard
Oxheart Carrot
Lincoln Peas
Henderson Bush Lima Beans
Daraju Kale
Potatoes
Early January Wakefield Cabbage
White Creole Onion
Pennsylvania Dutch Crookneck Squash
Green Arrow Peas
Scarlet Ohno Turnip
Kohlrabi
Strawberry Blite
Parsnips
Rutabaga
Collard Greens
Amaranth
Radishes - Cherry Bell and French Breakfast varieties listed.
Detroit Dark Red Beets
Younger people may not have heard of some of these vegetables. Mainstream agriculture prioritize speed, consistency, ease of harvest and transport. Likewise, tastes in food has changed and some of these were left behind. You may not find these strudy plants at your local garden center, but you can order the seeds if you can't find them there.
See something you have never tried? See if someone at a local Farmers Market sells it, or try a "gourmet" or ethnic market.
Note that a number of photos don't exactly follow the narrative. I saw Purslane in there with no context to it.
On this list, what do I plant?
