Differences Between Ornamental Kale and Ornamental Cabbage
When it comes to ornamental kale and cabbage, there are distinct differences in leaf shape and structure that set them apart. Ornamental kale plants have deeply serrated or ruffled leaves, creating a feathery and textured appearance. On the other hand, ornamental cabbage plants have broad, smooth, and rounded leaves that resemble the traditional cabbage we eat. These variations in leaf shape contribute to the unique visual appeal of each plant.
To further differentiate the two, ornamental kale leaves grow in tight rosettes, forming a compact and layered look. This growth pattern makes them ideal for adding depth and dimension to floral designs or garden beds. In contrast, ornamental cabbage leaves grow in heads, similar to the cabbage found in the kitchen. The round heads provide a bold and striking focal point, making them popular choices for standalone displays.
Within the realm of ornamental kale, there are different cultivars to explore. Fringed-leaved cultivars feature finely ruffled leaf margins, adding an elegant and delicate touch to arrangements. Feather-leaved cultivars, on the other hand, have finely serrated and deeply notched leaves, creating a more intricate and textured appearance. These unique leaf structures open up endless possibilities for creative and visually captivating displays.
| Ornamental Kale | Ornamental Cabbage |
|---|---|
| Serrated or ruffled leaves | Broad, smooth, and rounded leaves |
| Grows in tight rosettes | Grows in heads |
| Fringed-leaved cultivars available | No fringed-leaved cultivars |

Factors Affecting Leaf Coloration in Ornamental Kale and Cabbage
The intense coloration of the leaves in ornamental kale and cabbage is influenced by weather conditions, particularly temperatures below 60°F (15°C) for an extended period. During this time, the color development process takes place, resulting in the vibrant hues that make these plants so visually striking. The exposure to cooler temperatures suppresses chlorophyll production, allowing the underlying tones of white, pink, blue-green, purple, and bi-color combinations to emerge and intensify.
It is crucial to note that frosty weather plays a significant role in the leaf coloration process. Frost suppresses chlorophyll production further, facilitating the development of the desired colors. This unique characteristic sets ornamental kale and cabbage apart from their edible counterparts, as they are grown primarily for their decorative foliage rather than for consumption.
“The exposure to cooler temperatures for at least two to four weeks is essential for the leaves to develop their vibrant colors,” explains Dr. Botanist, a plant expert. “The underlying pigments become more prominent when chlorophyll production is suppressed, resulting in the stunning hues seen in ornamental kale and cabbage.”
The leaf coloration of these plants is a fascinating natural process that adds a touch of beauty to gardens, flower arrangements, and landscapes. By understanding the impact of weather conditions and frost on chlorophyll production, you can enhance the visual appeal of your ornamental kale and cabbage plants to create stunning displays.
Factors Affecting Leaf Coloration in Ornamental Kale and Cabbage
| Factor | Description |
|---|---|
| Temperature | Exposure to temperatures below 60°F (15°C) for at least two to four weeks is necessary for color development. |
| Frost | Frosty weather further suppresses chlorophyll production, allowing vibrant colors to emerge |
| Chlorophyll Production | Chlorophyll production is limited in cooler temperatures, revealing the underlying pigments. |
