Why You'll Love It
Flowering Kale isn't your typical leafy green; it's a burst of color designed to thrive in cooler temperatures when many other flowers fade. Its ruffled leaves, which intensify in vibrant shades of pink, purple, cream, and white, offer a stunning visual display. Gardeners adore it for its resilience and ability to add interest to borders, containers, and window boxes throughout the fall and winter months.
Flowering Kale provides texture and form to landscapes, creating eye-catching displays. Its long-lasting color makes it a popular choice for seasonal decorations, offering beauty when other blooms are scarce. The plant's unique aesthetic appeals to those seeking low-maintenance beauty.
The Story
Flowering Kale, scientifically known as Brassica oleracea, is a cultivated variety of kale, originating from the wild cabbage found along the Mediterranean coast. While its exact origins are debated, it has been cultivated for centuries, primarily as a food source. However, breeders eventually selected for ornamental qualities, resulting in the vibrant colors and frilly textures we see today.
Flowering Kale doesn't have a rich cultural significance like some other flowers, but it has become a symbol of fall and winter gardens, representing resilience and beauty in the face of colder weather. It's often associated with Thanksgiving and autumn festivals, adding a touch of festive cheer to seasonal displays. Its popularity has spread worldwide, making it a staple in cool-climate gardens.
Complete Care Guide
Flowering Kale thrives in cool temperatures (40-70°F) and requires at least 6 hours of sunlight daily. Plant in well-draining soil, enriched with compost or other organic matter. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant color.
Deadhead any spent leaves to encourage new growth and maintain a tidy appearance. Protect from extreme cold or frost, especially in colder climates. Mulch around the base of the plant to retain moisture and regulate soil temperature. Monitor for pests like aphids and cabbage worms, and treat as needed. Proper air circulation helps prevent fungal diseases.
Light Requirements
Flowering Kale needs at least six hours of direct sunlight per day to develop its best color. Insufficient light can lead to leggy growth and dull coloration. When planting, choose a location that receives full sun exposure. If growing in containers, rotate the plants regularly to ensure even light exposure on all sides.
In regions with shorter daylight hours, consider using supplemental lighting, such as grow lights, to extend the plant's exposure to light. This is particularly important for maintaining vibrant colors. East-facing locations are often a good choice, providing morning sun without the intense afternoon heat.
Seasonal Care
Spring
In spring, plant seedlings outdoors after the last frost. Prepare the soil with compost and ensure good drainage. Monitor for pests as they become more active.
Summer
Flowering Kale prefers cooler temperatures, so provide shade during the hottest part of the summer. Water regularly to prevent heat stress.
Fall
Fall is the prime season for Flowering Kale. Ensure adequate sunlight and regular watering to encourage vibrant color development. Fertilize every 2-3 weeks.
Winter
Protect from extreme cold and frost. Mulch around the base of the plant to insulate the roots. Water sparingly during periods of freezing temperatures.
The Life of Your Flowering Kale
Seedling / Juvenile
Start seeds indoors 6-8 weeks before the first expected frost. Use a well-draining seed-starting mix. Provide ample light, either natural or supplemental, to prevent leggy seedlings. Harden off the seedlings before transplanting outdoors.
Adolescent
As the plant develops, provide consistent moisture and regular fertilization to encourage robust growth. Monitor for pests and diseases. Ensure adequate spacing between plants to promote good air circulation.
Mature
During the active blooming (coloring) period, maintain consistent watering and fertilization. Protect from extreme temperatures. Deadhead any spent leaves to maintain a tidy appearance and encourage continued color development.
Established
After the colorful display fades, Flowering Kale may bolt (produce flower stalks). Remove the flower stalks to prolong the plant's life. While reblooming is unlikely, the plant can still provide interesting foliage.
Propagation Guide
Flowering Kale is primarily grown from seed, but propagation through stem cuttings is possible, though less common. Take stem cuttings from healthy, non-flowering shoots in late summer or early fall. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and in a warm, humid environment until roots develop.

Expert Knowledge
For the most intense color, expose Flowering Kale to cooler temperatures (below 50°F). Avoid planting in overly fertile soil, as this can promote excessive leaf growth at the expense of color. Choose varieties with different leaf textures and colors to create a visually dynamic display. Regularly deadhead spent leaves to maintain a tidy appearance. Consider companion planting with other cool-season ornamentals.
Troubleshooting
Yellow leaves
Yellow leaves can indicate overwatering, underwatering, or nutrient deficiency. Adjust watering accordingly and fertilize with a balanced fertilizer.
Brown leaf edges
Brown leaf edges often indicate dry air or inconsistent watering. Increase humidity and ensure consistent soil moisture.
Drooping leaves
Drooping can be caused by underwatering, heat stress, or root rot. Water thoroughly, provide shade during the hottest part of the day, and check for signs of root rot.
Root rot
Root rot is caused by overly wet soil. Improve drainage, use well-draining soil, and avoid overwatering. Treat with a fungicide if necessary.
Pests
Aphids and cabbage worms are common pests. Treat with insecticidal soap or neem oil. Handpick larger pests like cabbage worms.
