An Italian heirloom, Tuscan or Lacinato kale has a long tradition in Tuscan cuisine, where it can be found in nearly every garden. Thomas Jefferson grew it in his garden at Monticello.
Dark blue-green to black leaves with a heavily crinkled or blistered texture inspire one of its common names, Dinosaur kale. Tender leaves have a softer texture than curly green kales. Thought by many to be the tastiest kale.
