What is Ornamental Cabbage?
Ornamental cabbage, also known as flowering kale, is a cultivar of Brassica oleracea, the same species that gives us edible cabbage, broccoli and cauliflower. While it’s technically edible, ornamental cabbage is grown for its stunning foliage rather than its taste.
Key Features:
- Large, showy leaves in shades of white, pink, purple and green
- Rosette growth pattern resembling a giant flower
- Cold-hardy, thriving in fall and winter temperatures
- Available in various sizes, from 6 inches to 2 feet in diameter
When and Where to Plant Ornamental Cabbage
Timing:
Plant ornamental cabbage in late summer or early fall, about 6-8 weeks before the first frost in your area. This timing allows the plants to mature as temperatures cool, which intensifies their colors.
Location:
- Choose a spot with full sun to partial shade
- Well-draining soil is essential
- Can be planted in garden beds, borders, or containers
How to Plant Ornamental Cabbage
- Prepare the soil by loosening it and adding organic matter.
- Space plants 12-18 inches apart, depending on the variety.
- Plant at the same depth as they were in their nursery containers.
- Water thoroughly after planting.
Caring for Your Ornamental Cabbage
Watering:
- Keep soil consistently moist but not waterlogged
- Water at the base of the plant to avoid wetting the leaves
Fertilizing:
- Feed with a balanced, water-soluble fertilizer every 2-3 weeks
- Stop fertilizing once the plants are fully grown
Temperature:
- Ornamental cabbage thrives in cool temperatures (45-60°F / 7-15°C)
- Colors intensify after exposure to frost
Pest Control:
- Watch for common cabbage pests like aphids and cabbageworms
- Use insecticidal soap or neem oil for organic pest control

Harvesting and Using Ornamental Cabbage
While ornamental cabbage is grown primarily for its looks, it is edible. However, it’s not as palatable as its culinary cousins. If you decide to eat it:
- Harvest outer leaves as needed
- Wash thoroughly before consumption
- Use young, tender leaves in salads or as garnishes
- Cook older leaves as you would regular cabbage
