In a thread of mine, someone mentioned something called 'succulent greens.' I've been curious about what these are, and if native, wild plants in my backyard would be considered succulent greens? I've been looking many of the plant species up and I've learned we've got a mixture of plains and wetlands plants. I live in the Arkansas River Valley of Oklahoma, and our yard stays damp and shady in many spots. When it rains, low spots stay wet for days, if not weeks, at a time.
Here are some of the plants I can identify;
purple dead nettle/henbit deadnettle,
purple star creepers,
These are some of the things I can identify through google search, and some of these the chickens don't eat (they dont like dandelions for sure).
In any case, are these succulent greens? If not, what are succulent greens? Is it the plant 'succulent' or things like spinach or kale?
