Lacinato kaleBrassica oleracea var. palmifolia

Lacinato kale, often called 'Cavolo Nero', is an ancient leafy green from Tuscany. With its nearly black, puckered leaves growing in a palm-like rosette, it serves as both a culinary delicacy (essential for Ribollita) and a striking ornamental for the garden. Unlike curly kale, it offers a milder flavor and maintains an excellent texture even after vigorous cooking.

Main harvest period Harvesting after the onset of frost improves the flavor.

Remove

  • Lower, fully developed leaves for consumption
  • Dead or yellowing leaves at the base
  • Flower buds in the first year (if bolting prematurely)

Preserve

  • Central growing point (heart)
  • Young, developing leaves in the upper section

Avoid

  • Stripping the plant bare (always leave enough foliage)
  • Damaging the central leader

Tools and hygiene

Use clean knives to prevent rot on the main stalk.

Harvest
Harvest window

Late summer until the end of winter.

Optimal harvest time

After the first frost for a milder, sweeter flavor.

Harvest details
Harvest frequency

Continuous from the bottom up.

Harvest indicators
  1. Leaves have reached a length of approx. 20-30 cm
  2. Dark green, almost bluish-black coloration
  3. Typical crinkled (bumpy) texture is fully developed
Post harvest handling

Place leaves in cold water or store in the refrigerator immediately after harvest to prevent wilting.

Short-term storage (fresh) or freezing

Storage life

Fresh in the refrigerator approx. 5-7 days; frozen (after blanching) up to 10 months.

  2. Drying into kale chips
  3. Preserving (Pesto)
Processing use
Main uses
  1. Steamed as a side dish
  2. Ingredient in stews (e.g., Ribollita)
  3. Raw in thin strips for salads
Kitchen usage
Preparation tips

The tough central ribs should be removed before cooking.

Flavor profile

Mildly spicy, less bitter than curly kale, with a slightly nutty note.

Safety and edibility
Edible parts
  1. Leaves
  2. Young flower buds (similar to broccoli)
Inedible or caution parts
  1. Tough, woody stalks
Toxicity notes

Non-toxic. Like all brassicas, it contains glucosinolates, which may cause bloating in sensitive individuals.

Raw consumption

Possible and healthy; young leaves are more tender for raw consumption.

Seed saving
Isolation distance meters1000
Minimum population size20
Seed viability years5
Seed saving advanced
Method

Overwinter plants, allow to flower in the second year, and harvest the pods (siliques) after they have turned brown.

Purity notes

Extremely high risk of cross-pollination with all other Brassica oleracea species (kohlrabi, broccoli, cauliflower).

Varieties
  1. NameNero di Toscana
    Description

    The classic heirloom variety from Italy with very dark, heavily crinkled leaves.

  2. NameBlack Magic
    Description

    Improved selection with particularly uniform growth and good winter hardiness.

Woody crop details
Notes

Not woody in the horticultural sense, but the plant develops a stable, palm-like stalk over the course of the season.

Ecology
Pollinator valuehigh
Wildlife valuemedium
Biodiversity notes

If allowed to flower in its second year, it provides excellent forage for bees. Cabbage white caterpillars use it as a host plant.
