The only thing that I might add is, what about Chufa? See the article, "The Superfood They Turned Into a Weed: Why Is It Illegal to Grow This?," - https://www.freedomsphoenix.com/News/388186-2025-12-08-the-superfood-they-turned-into-a-weed-why-is-it.htm. This might be a good way to start this 'illegal' food plant, especially in areas where the soil is too poor for regular crops.
