Overview

Brassica oleracea 'Lacinato' is Lacinato kale (dinosaur kale, cavolo nero), a cool-season annual forming an upright rosette 18-24 inches (45-60 cm) tall and 12-18 inches (30-45 cm) wide. Narrow strap-shaped dark blue-green to near-black leaves 2-3 inches (5-7 cm) wide and 8-12 inches (20-30 cm) long with a heavily blistered (savoyed) pebbled surface and prominent white to pale green midribs. The flat strap-shaped leaves distinguish Lacinato from curly kale types. In the mustard family (Brassicaceae). Known as 'cavolo nero' (black cabbage) in Italian — cultivated in Tuscany since at least the 18th century. Cool-season crop: bolts in sustained heat above 80°F (27°C). The flavor and leaf tenderness improve after frost exposure — fall- and winter-harvested leaves are sweeter. Sow in early spring or late summer for fall harvest. Harvest outer leaves by cut-and-come-again starting at 30-35 days; full-size at 60-75 days. The species B. oleracea also includes cabbage, broccoli, and cauliflower. All Brassica contain goitrogens — reduced by cooking. Cabbage worms (Pieris rapae), aphids, and flea beetles are the primary pests. Not deer-resistant. Non-toxic (edible crop). Full sun to partial shade. Annual. Growth rate is moderate.

Native Range

Cultivar from Tuscany, Italy (cultivated since at least the 18th century). The species B. oleracea is native to Mediterranean and Atlantic coastal Europe.

Suggested Uses

Grown in vegetable gardens, raised beds, and containers of at least 5 gallons (19 L). Cool-season crop — spring and fall harvests. Italian heirloom (cavolo nero). Flavor improves after frost. Not deer-resistant. Non-toxic. Annual.

How to Identify

Identified by narrow strap-shaped dark blue-green to near-black leaves with a heavily blistered pebbled surface and white midribs in an upright rosette. The flat strap shape and the near-black color with blistered texture distinguish Lacinato from curly kale types. In Brassicaceae.

Bolts in sustained heat or in the second year — bright yellow 4-petaled cruciform flowers in terminal clusters. Bolting makes leaves bitter and tough. Flowering is undesirable in a leaf crop. Pinch flower buds to extend harvest.
