Because of the frilly appearance of the leaves, all varieties of Kale can be used as a garnish to decorate food dishes and platters. However, Purple Kale is particularly decorative, due to the red and green colors in the leaves. Kale can be substituted with Collard Greens, Flowering Kale, Swiss Chard, Rapini, or Mustard Greens. Some of the other varieties of Kale include: Curley, Dinosaur (also known as Black Cabbage, Black Kale, Lacinato Kale, Black Tuscan Palm Tree Kale, or Cavolo Nero), Red Russian (also known as Ragged Jack Kale), and Purple Flowering Kale (also known as Ornamental Kale or Flowering Cabbage).
