Why You'll Love It
Ornamental Cabbage, also known as flowering kale, is a captivating addition to any garden or landscape, particularly during the cooler months. Its vibrant colors, ranging from creamy whites and rosy pinks to deep purples, offer a stunning visual display when many other plants are dormant. The ruffled or frilly leaves create a unique texture that adds dimension and interest.
Plant lovers adore Ornamental Cabbage for its resilience and ability to thrive in cooler temperatures. It provides a splash of color and life when most other annuals have faded. Whether used as a focal point in containers, massed in garden beds, or incorporated into mixed plantings, Ornamental Cabbage delivers a bold statement that is both elegant and eye-catching. Its versatility and beauty make it a favorite among gardeners seeking to extend the growing season with a touch of dramatic flair.
The Story
Ornamental Cabbage and kale (Brassica oleracea) share the same botanical species as edible cabbage and kale, but they have been selectively bred for their ornamental value rather than their taste. Originating from wild cabbage found along the Mediterranean coast, these plants have a long history of cultivation, dating back to ancient Greece and Rome.
Over centuries, breeders focused on developing varieties with intensely colored leaves, resulting in the diverse range of ornamental cabbages and kales we see today. While primarily grown for their aesthetic appeal, they are technically edible, although their flavor is often bitter compared to their culinary counterparts.
Ornamental Cabbage gained popularity in the West during the 19th century and has since become a staple in fall and winter gardens. In some cultures, they symbolize prosperity and good fortune, adding a layer of cultural significance to their visual charm.
Complete Care Guide
Ornamental Cabbage thrives in cool weather and requires well-draining soil rich in organic matter. Plant in a location that receives at least 6 hours of sunlight daily, especially in the fall and winter when sunlight is less intense. Water regularly, keeping the soil consistently moist but not waterlogged.
Fertilize every 2-3 weeks with a balanced liquid fertilizer to encourage vibrant leaf color. Protect from extreme cold snaps with a frost cloth if necessary. Remove any yellowing or damaged leaves to maintain appearance and prevent disease. Deadheading is not required as these plants are grown for their foliage rather than flowers.
Ensure good air circulation around the plants to minimize the risk of fungal diseases. Monitor for pests like aphids and cabbage worms, and treat as needed with insecticidal soap or neem oil. With proper care, Ornamental Cabbage will provide a stunning display of color throughout the cooler months.
Light Requirements
Ornamental Cabbage requires at least six hours of direct sunlight daily to develop its vibrant colors. In the fall and winter, when sunlight is less intense, a location with full sun exposure is crucial. Insufficient light can result in faded colors and leggy growth.
If growing in containers, position them in the sunniest spot available. Consider using grow lights if natural light is limited, especially indoors. Rotate plants regularly to ensure even light exposure on all sides.
When planting in the garden, choose a site that is not shaded by trees or buildings during the peak sunlight hours. South-facing locations are generally ideal for maximizing light exposure.
Seasonal Care
Spring
As temperatures rise in spring, Ornamental Cabbage will begin to decline. Remove the plants and compost them.
Summer
Ornamental Cabbage does not thrive in summer heat. Focus on preparing for fall planting by selecting seeds and preparing the garden bed.
Fall
Plant Ornamental Cabbage seedlings in the fall for best color development. Provide consistent watering and fertilization.
Winter
Protect Ornamental Cabbage from extreme cold snaps with frost cloth. Continue regular watering and fertilization as needed.
The Life of Your Ornamental Cabbage
Seedling / Juvenile
Start Ornamental Cabbage seeds indoors 6-8 weeks before the first expected frost. Provide ample light and consistent moisture. Transplant seedlings outdoors once they have developed several true leaves and the soil has cooled.
Adolescent
As the plant develops, maintain consistent watering and fertilization. Monitor for pests and diseases. Ensure adequate sunlight to promote vibrant color development.
Mature
During the active blooming period (foliage color development), continue regular watering and fertilization. Remove any yellowing or damaged leaves to maintain appearance.
Established
Ornamental Cabbage is typically grown as an annual and does not rebloom. After the cold season, the plant will naturally decline. Remove the plant and compost it.
Propagation Guide
Ornamental Cabbage is typically grown from seed, as propagation through other methods is not common.
Here's a guide for growing from seed:
1. Start seeds indoors 6-8 weeks before the last expected frost.
2. Sow seeds in seed-starting mix and keep consistently moist.
3. Provide ample light or use grow lights to prevent leggy growth.
4. Harden off seedlings gradually before transplanting outdoors.
5. Transplant seedlings into well-draining soil in a sunny location.
Division, stem cuttings, and keiki production are not applicable to Ornamental Cabbage propagation.
Expert Knowledge
For the most intense color, ensure Ornamental Cabbage is exposed to temperatures consistently below 60°F (15°C). The cool temperatures trigger the development of the vibrant hues. Choose varieties that are known for their strong color and resilience. Amend the soil with plenty of organic matter to improve drainage and nutrient availability. Consider using a slow-release fertilizer at planting time to provide a steady supply of nutrients. Regularly inspect plants for pests and diseases to prevent problems before they escalate.
Troubleshooting
Yellow leaves
Yellow leaves can indicate overwatering, underwatering, or nutrient deficiency. Adjust watering practices and fertilize with a balanced fertilizer.
Brown leaf edges
Brown edges may be caused by dry air or salt buildup in the soil. Increase humidity around the plant and flush the soil with water.
Drooping leaves
Drooping can be a sign of underwatering or root rot. Check soil moisture and drainage. Adjust watering accordingly.
Root rot
Root rot is caused by overwatering and poor drainage. Improve drainage and allow the soil to dry out between waterings. Treat with a fungicide if necessary.
Pests
Pests like aphids and cabbage worms can damage Ornamental Cabbage. Treat with insecticidal soap or neem oil.
