Kale is a cool-season vegetable that's high in nutrients, low in calories, and very tolerant of frost. Offering a range of colors and shapes, many varieties, although just as edible and delicious as the plainer types, are grown mainly for their beautiful ornamental leaves, which are brilliant red, pink, lavender, blue, violet, or white in the interior. When choosing a kale, keep in mind that green ones tend to be sweeter, while red varieties are somewhat more appealing to the eye. Red kale also contains anthocyanins, an antioxidant!
