Kale (Lacinato), also known as dinosaur kale, cavolo nero, or Tuscan kale, is a heritage Italian variety that chefs and home gardeners prize above all other kales for its more nuanced, less bitter flavor and its stunning visual texture — deep blue-green leaves that ripple like leather, each one pocked with small bumps. Unlike curly kales that can taste harsh when raw, Lacinato holds up beautifully in salads after a light massage with olive oil and salt, as well as in soups, stews, and the classic Tuscan ribollita. The flavor genuinely improves after the first autumn frost, as cold temperatures convert starches to sugars — so late-season harvests in zones 5–7 are the sweetest of the year.
Lacinato kale is best transplanted in early spring (4–6 weeks before last frost) or midsummer for a fall and winter harvest. Transplants establish faster than direct-seeding and produce larger, more uniform leaves. Space plants 12–18 inches apart — kale appreciates airflow, and crowded plants grow leggy. Apply a 2-inch layer of compost at planting time; kale is a heavy feeder and responds noticeably to rich soil. Water consistently at about 1–1.5 inches per week; drought stress makes leaves tough and intensifies bitterness. The biggest pest to watch is the imported cabbageworm (white butterfly caterpillars); apply Bacillus thuringiensis (Bt) spray at first sign, or use floating row cover as prevention. Harvest outer leaves from the bottom of the plant working upward — never strip the growing crown. In zones 6–9, Lacinato will overwinter with minimal protection and resume growth in early spring, giving you a second harvest wave.
