Dinosaur kale goes by a number of names, including dino kale, Tuscan kale, Lacinato kale, black kale, and cavolo nero (Italian for "black cabbage"). It is a member of the cabbage family, but of the leafy variety, with long, palm-like fronds that can grow up to 3 feet long. An incredibly hearty cooking green, the dark, almost blue-green or even black-green leaves are ruffled and, just like other varieties of kale, have distinct ribs.
