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.

Spacing
Spacing notes
Good air circulation prevents fungal diseases.
Growth dimensions
Final size notes
The palm-like growth habit develops during the course of the summer.
Temperature
Temperature notes
Tolerates frosts down to approx. -10°C to -15°C.
Water
Critical water phases
- Establishment phase after planting
- Main growth phase in midsummer
Water notes
Consistent moisture prevents premature bolting.
Nutrition
Nutrition notes
Brassicas require plenty of lime and sulfur for healthy growth.
Container
Container notes
Very decorative in sufficiently large containers.
Support
Support notes
In windy locations, a short stake can provide stability.
Cultivation modes
Yield density
Yield notes
Yield depends heavily on the harvest duration and fertilization.
Site
Sun exposure
Full sun to partial shade
Wind protection
Advantageous but not mandatory
Climate suitability
Very well suited for temperate European climates; frost hardy.
Soil
Soil type
Medium-heavy, loamy-humus
PH range
Soil notes
Prefers deep soil with good water retention.
Watering
Frequency
Regularly, never let the soil dry out completely.
Quality
Tap water or rainwater suitable.
Nutrition
Primary fertilizer
Rotted manure or compost in spring.
Supplementary fertilizer
Organic liquid fertilizer or horn meal during the season.
Cultivation planning
Succession sowing
Bed planning notes
Good neighbors: Peas, beans, lettuce, tomatoes. Poor neighbors: Other brassicas.
Crop rotation
Preceding crops
- Peas
- Beans
- Early potatoes
- Spinach
Subsequent crops
- Carrots
- Beetroot
- Lettuce
- Celery
Notes
To avoid clubroot, a crop rotation break of at least 4 years from other brassicas should be observed.
Deficiencies
Nitrogen
Pale green to yellowish older leaves, stunted growth.
Boron
Hollow stems, internal browning.
Problems
Environmental
Name
Premature Bolting
Cause
Stress caused by cold or drought.
Problem management
Common pest groups
- Caterpillars
- Aphids
- Flea beetles
Common disease groups
- Soil-borne fungi
- Leaf spot diseases
Prevention principles
- Use of crop protection nets from planting onwards.
- Balanced fertilization without nitrogen excess.
- Regular hoeing to disrupt pest cycles.
Diagnosis notes
Regularly check the undersides of leaves for egg clusters.

Profiles
- SlugclubrootSeveritycritical
Conditions
- Acidic soil
- Waterlogging
- Lack of crop rotation
Affected parts
- Roots
- Whole plant
Prevention
- Liming the soil
- Maintain crop rotation
Organic control
- No direct control possible; dispose of infected plants in household waste.
Diagnostic rules
Symptom
Holed leaves in young plants
Possible causes
- Flea beetles
- Slugs
First checks
- Look for small jumping beetles
- Search for slime trails
Prevention strategy
Cultural
- Wide spacing for quick drying.
- Optimal potassium supply for cell stability.
Monitoring
- Weekly check for cabbage white eggs.
Organic first response
- Hand-picking caterpillars.
- Use of beneficial insects like parasitic wasps.
Notes
Nets with mesh size < 0.8 mm also protect against cabbage fly.
Diagnosis
Common misdiagnoses
Nitrogen deficiency is often mistaken for water stress.
Phenology
Stages
- Germination
- Seedling stage
- Leaf development and palm-like growth
- Overwintering (Vegetative phase)
- Bolting and flowering (in the second year)
- Seed maturation
Notes
As a biennial plant, Lacinato kale produces edible leaves in the first year and only flowers in the following year after a period of cold.

Harvest details
Harvest frequency
Continuous from the bottom up.
Harvest indicators
- Leaves have reached a length of approx. 20-30 cm
- Dark green, almost bluish-black coloration
- 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.

Storage details
General storage category
Short-term storage (fresh) or freezing
Storage life
Fresh in the refrigerator approx. 5-7 days; frozen (after blanching) up to 10 months.
Processing options
- Blanching and freezing
- Drying into kale chips
- Preserving (Pesto)
Processing use
Main uses
- Steamed as a side dish
- Ingredient in stews (e.g., Ribollita)
- 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
- Leaves
- Young flower buds (similar to broccoli)
Inedible or caution parts
- 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
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
- NameNero di Toscana
Description
The classic heirloom variety from Italy with very dark, heavily crinkled leaves.
- 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
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.
