Daubenton's Kale

Brassica oleracea var. acephala

vegetable

Daubenton is a perennial kale variety originating from France, known for its ability to regrow after harvesting and produce leaves year-round in mild climates. Unlike annual kales, it develops a woody stem and can live for multiple years, continuously sprouting new leaves from the top. It's an heirloom variety prized by gardeners for its productivity and cold hardiness.

Growth Stages

1

Seedling

3-4 weeks

Small plantlets with 2-4 true leaves emerging; tender and delicate.

Keep soil consistently moist, provide bright light, thin seedlings to prevent crowding, protect from wind.

2

Establishment

4-6 weeks

Young plant developing a sturdy stem and multiple leaves; 6-12 inches tall.

Harden off transplants gradually, plant out after last frost, mulch around base, water regularly, support with a stake if needed.

3

Vegetative Growth

6-8 weeks (first year); continues indefinitely in perennial growth

Plant develops robust stem and abundant foliage; can reach 3-4 feet tall depending on conditions.

Apply balanced fertilizer monthly, maintain consistent watering, mulch to retain moisture and suppress weeds, watch for pests, remove damaged leaves.

4

Harvesting & Maintenance

Ongoing; 2-3 years per plant

Plant produces harvestable leaves continuously; stem becomes increasingly woody over seasons.

Begin harvesting when plant is 12-18 inches tall, remove lower leaves first, leave top 5-6 leaves to support growth, continue harvesting throughout season and over winter in mild climates.

5

Perennial Management

Year 2-4+

Established plant with thick woody stem, multiple new growth points, and year-round leaf production.

In spring, prune hard to encourage bushy new growth and remove old diseased wood, top-dress with compost, maintain water during dry spells, replace plants after 3-4 years if productivity declines.

🍳

Long-Term Harvest

Culinary

Unlike annual kales, Daubenton's perennial nature allows continuous harvesting from a single plant for years, providing fresh greens without replanting annually. [source]

💊

Nutritional Powerhouse

Medicinal

Rich in vitamins K, C, and A, plus calcium, iron, and antioxidants. Regular consumption supports bone health, immune function, and anti-inflammatory benefits typical of brassicas. [source]

🦋

Wildlife Support

Wildlife

Kale flowers (which appear if plant is allowed to bolt) attract pollinators and beneficial insects. The plant also provides shelter and food for garden fauna. [source]

Harvest Tips

Begin harvesting when plant is 12-18 inches tall by removing outer leaves from the bottom up, leaving the top 5-6 leaves intact to support continued growth. Harvest regularly to encourage new leaf production. Young leaves are more tender; older outer leaves are tougher but still edible. In mild climates, harvesting can continue through fall and winter. A single plant can provide leaves for several years with proper maintenance.

Fun Facts

  • 🌱 Daubenton kale was developed in France in the 19th century and is sometimes called 'Thousand-Headed Kale' because of its prolific regrowth and multitude of harvestable leaves.
