Perennial cabbage is a long-lived, cold-hardy vegetable that produces edible leaves and flower shoots year after year—unlike traditional annual cabbage. If you’re tired of replanting cabbage every season, this resilient plant offers a sustainable, low-maintenance alternative. With proper care, some varieties can thrive for 5–10 years in your garden.
Whether you’re a homesteader, permaculture enthusiast, or just want to grow food with less effort, perennial cabbage is a smart addition to your edible landscape. It’s packed with nutrients, adapts well to various climates, and requires minimal inputs once established.
Quick Answer: Key Facts About Perennial Cabbage
- Lifespan: Grows for multiple years (typically 5–10), unlike annual cabbage.
- Edible Parts: Leaves, flower stalks (broccoli-like), and young shoots.
- Climate Tolerance: Thrives in USDA zones 6–9; some varieties survive zone 5.
- Maintenance: Low—requires little watering or fertilizing after establishment.
- Harvest Time: Spring and early summer for flower shoots; leaves year-round in mild climates.
Types of Perennial Cabbage You Should Know
Not all cabbage is annual. Several perennial brassicas offer unique flavors and growing advantages. Here are the most popular types:
1. Walking Stick Cabbage (Brassica oleracea var. acephala ‘Walking Stick’)
This striking variety grows a tall, woody stem that can reach 6 feet. The stem is dried and used as a walking stick—hence the name. The leaves and flower shoots are edible and taste similar to kale.
2. Taunton Delecarlia (Brassicaoleracea ‘Taunton Delecarlia’)
A hardy, multi-stemmed perennial with large, crinkled leaves. It produces tender broccoli-like shoots in spring and tolerates heavy clay soils.
3. Nine Star Perennial Broccoli
Despite the name, this is a type of perennial cabbage that produces multiple broccoli-like heads over several years. Each plant yields 6–9 flower heads before going dormant.
4. Sea Kale (Crambe maritima)
Though not a true cabbage, sea kale is a perennial brassica with cabbage-like leaves and edible flower stalks. It’s salt-tolerant and perfect for coastal gardens.
How to Grow Perennial Cabbage: Step-by-Step
Growing perennial cabbage is simple once you understand its needs. Follow these steps for a thriving, long-term crop.
1. Choose the Right Variety
Match the plant to your climate and space. Walking Stick Cabbage needs room to grow tall, while Nine Star Broccoli works well in smaller beds.
2. Prepare the Soil
Perennial cabbage prefers well-drained, fertile soil with a pH between 6.0 and 7.5. Add compost before planting to boost organic matter.
3. Planting Method
- Seeds: Start indoors 6–8 weeks before last frost. Transplant when seedlings are 4–6 inches tall.
- Root cuttings or divisions: Many perennials can be propagated from root sections. Plant in early spring.
4. Spacing and Sunlight
Space plants 18–24 inches apart. They need full sun to partial shade—at least 6 hours of sunlight daily.
5. Watering and Mulching
Water regularly during the first growing season. Once established, they’re drought-tolerant. Apply mulch to retain moisture and suppress weeds.
6. Winter Care
In colder zones, protect plants with straw or burlap. Cut back dead foliage in late fall to prevent disease.
Harvesting Perennial Cabbage: When and How
Timing is everything. Harvest at the right stage for the best flavor and plant longevity.
Leaves
Pick outer leaves as needed throughout the growing season. Avoid stripping the plant—leave at least 4–6 leaves to sustain growth.
Flower Shoots (Broccoli-Like Heads)
Harvest in spring when shoots are 4–6 inches tall and buds are tight. Cut just below the head with a sharp knife. New shoots may form from the base.
Regrowth and Longevity
After flowering, the plant may go dormant. Don’t remove it—many perennials regrow from the root crown the following year.
Common Mistakes When Growing Perennial Cabbage
Even experienced gardeners make these errors. Avoid them for a healthier, longer-lasting crop.
- Planting in poor drainage: Perennial cabbage hates soggy roots. Raised beds help in wet climates.
- Overharvesting leaves: Removing too many leaves weakens the plant. Follow the “one-third rule.”
- Ignoring pests: Cabbage worms and aphids love brassicas. Use row covers or organic sprays like neem oil.
- Not dividing overcrowded plants: Every 3–4 years, divide clumps to maintain vigor.
- Planting in full shade: While tolerant of partial shade, too little sun reduces yield and flavor.
Pro Tips for Maximum Yield and Longevity
Get the most out of your perennial cabbage with these expert-backed strategies.
- Companion plant with herbs: Plant near thyme, rosemary, or sage to deter pests naturally.
- Feed lightly in spring: A balanced organic fertilizer (like compost tea) gives a boost without overstimulating growth.
- Save your own seeds: Let one plant flower and set seed. Harvest when pods dry and turn brown.
- Use cut stems as supports: Dried Walking Stick Cabbage stems make excellent plant stakes.
- Rotate planting sites: Avoid planting in the same spot where other brassicas grew recently to prevent soil-borne diseases.
Nutritional Benefits of Perennial Cabbage
Perennial cabbage isn’t just convenient—it’s a nutritional powerhouse.
| Nutrient | Benefit |
