'Nero di Toscana' is an Italian kale, aka Dinosaur or Lacinato kale. Much more upright with narrower leaves than other kales, it grows well in pots. Grow in sun to partial sun, though it produces the sweetest leaves in cooler weather. Cut off outer leaves only to prolong harvest. After the initial season of harvesting the leaves, don't pull out the plant. Chances are you'll get kale flowers in early spring, and those tops (sometimes sold as kale raab or rapini) are equally delicious, stir-fried or steamed.
