Kale and ornamental kale may sound like two distinct plants, but they are actually closely related. Both belong to the same species, Brassica oleracea, which also includes cabbage, broccoli, and cauliflower. However, there are some notable differences between kale and ornamental kale in terms of their appearance and usage.
1. Appearance:
Kale: Kale is characterized by its broad, flat leaves that grow in a loose rosette formation. The leaves may vary in color, ranging from deep green to purple or even bluish-green. Some varieties of kale have smooth edges, while others have curly or ruffled leaves.
Ornamental Kale: Ornamental kale, on the other hand, is specifically cultivated for its attractive appearance. It features deeply-cut, curly, frilly, or ruffled leaves, which often have vibrant colors such as pink, purple, white, or red. The leaves of ornamental kale are more ornate and decorative compared to regular kale.
2. Culinary Uses:
Kale: Regular kale is primarily grown for its nutritional value and is widely used in cooking. It has a slightly bitter flavor and a hearty texture, making it a popular ingredient in salads, stir-fries, soups, and smoothies. Kale is known for being rich in vitamins, minerals, and antioxidants.
Ornamental Kale: On the other hand, ornamental kale is not typically used for culinary purposes. While it is still edible, it is not as palatable as regular kale due to its more ornate appearance. Instead, ornamental kale is mainly grown for its aesthetic appeal and is often utilized in ornamental garden displays, containers, or as a colorful border plant.
3. Growing Preferences:
Kale: Regular kale is a hardy, cool-season crop that thrives in cooler climates. It can tolerate frost and even become sweeter after exposure to cold temperatures. Kale is relatively easy to grow and can be cultivated in a variety of soil types, although it prefers well-drained, fertile soil. It requires full sun to partial shade and regular watering.
Ornamental Kale: Similarly, ornamental kale also prefers cool weather and can withstand frost. It is often planted in the fall for colorful displays throughout the winter and early spring. Ornamental kale requires the same growing conditions as regular kale, including well-draining soil and adequate sunlight. However, since it is primarily grown for its visual appeal, it is often used as an annual plant and replaced after its display period.
Kale and ornamental kale are variations of the same plant species, but they differ in terms of appearance, culinary uses, and growing preferences. Regular kale is valued for its nutritional benefits and is commonly used in cooking, while ornamental kale is cultivated for its striking appearance and is mainly used as an ornamental plant. Whether you choose to grow kale for its health benefits or ornamental kale for its visual impact, both can add beauty and diversity to your garden or landscape.
