Ornamental cabbage, also known as flowering kale (Brassica oleracea), is a stunning cold-weather plant prized for its vibrant, colorful foliage. Unlike edible cabbage, it’s grown for its decorative leaves, which come in shades of pink, purple, white, and green. Perfect for fall and winter gardens, this hardy plant adds a pop of color when most flowers fade.
1. Choosing the Right Variety
Popular ornamental cabbage varieties include:
- ‘Chidori’ – Ruffled leaves with deep purple centers.
- ‘Osaka’ – Smooth leaves in pink, white, or red.
- ‘Peacock’ – Feathery, serrated leaves in mixed colors.
- ‘Nagoya’ – Tight rosettes with bright contrasting colors.
2. Planting Ornamental Cabbage
When to Plant
- Best time: Late summer to early fall (for autumn/winter color).
- Can also be planted in early spring in cooler climates.
Soil Requirements
- Well-draining, fertile soil (pH 6.0–7.5).
- Amend with compost for better growth.
Sunlight Needs
- Full sun (6+ hours daily) for best color.
- Tolerates partial shade but may have less intense hues.
Spacing
- Space plants 12–18 inches apart to allow proper growth.
3. Watering & Feeding
- Watering: Keep soil consistently moist but not soggy.
- Water deeply 2–3 times per week, depending on weather.
- Reduce watering in winter if rainfall is sufficient.
- Fertilizer:
- Use a balanced fertilizer (10-10-10) at planting.
- Avoid high-nitrogen fertilizers (can reduce leaf color).
4. Temperature & Hardiness
- Thrives in cool weather (40–60°F / 5–15°C).
- Can survive light frosts (colors intensify in cold).
- Prolonged freezing temperatures (<25°F / -4°C) may damage leaves.
5. Pest & Disease Control
Common Pests:
- Aphids – Spray with water or insecticidal soap.
- Cabbage worms – Handpick or use Bacillus thuringiensis (Bt).
- Slugs & snails – Use beer traps or diatomaceous earth.
Diseases:
- Powdery mildew – Improve air circulation, avoid overhead watering.
- Root rot – Ensure well-draining soil.
6. Pruning & Maintenance
- Remove yellow or damaged leaves to keep the plant healthy.
- Deadhead any flower stalks to prolong foliage beauty.
7. Using Ornamental Cabbage in Landscaping
- Container gardens (great for patios and balconies).
- Border edging or mass planting for dramatic effect.
- Fall & winter floral arrangements (long-lasting cut foliage).
