White kale is a short compact plant that produces contrasting white midribs within its frilly green leaves. The central leaves of the plant’s rosette become completely white when fully mature, giving it a "flower-like" look. White kale is rather strong flavored with a chewy texture. Its taste is reminiscent of cabbage with a robust earthy finish. Once cooked, White kale’s texture softens and its flavor becomes sweet and nutty.
