wildrose: The fact that kale, collards, cabbage, Brussel sprouts, broccoli, and cauliflower are all different cultivars of the same species always amazes me. At some point, historically speaking, they would have all been the same scrawny weed, but as a result of selective breeding they've developed into different useful forms. Brassica oleracea covers a lot of ground, but if you open it up to different species of Brassica then the list includes mustard, rapeseed, kale, napa cabbage, horseradish, turnip, rutabaga, radish, arugula, and more!
