Lamb’s Quarters (chenopodium album) is considered an edible weed. But go ahead and grow it on purpose. Put it with the kale and the lettuce; civilized like. Pampered, it’s much more tender, and cooked it is much tastier than spinach. Throw some radish greens into the mix. They’re prickly, but cooking sees to that. Oh, and add turnip tops; the bottoms do better in the fall anyway.
