I see marshmallow is on that list. It’s pretty finicky about growing conditions, but there are other mallows with the same medicinal properties that are easier to grow. Last fall I saw my planting of High Mallow finally took hold: https://strictlymedicinalseeds.com/product/mallow-high-malva-sylvestris-packet-of-50-seeds-organic/
The color in the two photos looks quite different. Are they both the same cultivar or are they different varieties?
