Look to Cabbage for Winter Color—and a Touch of Horticultural Magic
In stories of wizards and witches, transfiguration is described as the magic of turning one object into another. With the wave of a wand, a magician can turn a teacup into a hedgehog, a rabbit into a hat, or a human into a cat. Here in the real world, transfiguration remains impossible—mostly. One plant species seems to have the magical ability to transform into a bewildering variety of forms and shapes. You may have enjoyed one of these forms for dinner last night. You may be growing another in your flowerbeds. Brassica oleracea isn’t magic, but it may be as close as we muggles can get.
