In this article, we will delve into the world of ornamental kale, exploring its characteristics, growth habits, and most importantly, its drought tolerance.
Introduction to Ornamental Kale
Ornamental kale, also known as flowering kale, is a type of kale that is primarily grown for its decorative value rather than its edible leaves. It is a cool-season crop, which means it thrives in the cooler temperatures of spring or fall. This plant is a member of the Brassica family, which includes other popular ornamental plants like cabbage and broccoli. Ornamental kale is known for its stunning displays of color, ranging from deep purples and pinks to crisp whites and greens. Its frilly, curly, or flat leaves can add a dramatic touch to any garden bed, container, or floral arrangement.
Characteristics and Growth Habits
Ornamental kale is a relatively low-maintenance plant, making it an excellent choice for gardeners of all skill levels. It prefers well-draining soil and partial to full sun, although it can tolerate some shade. The ideal temperature for ornamental kale is between 60°F and 70°F (15°C and 21°C), making it an excellent choice for spring or fall gardens. This plant can grow quite large, reaching heights of up to 3 feet (90 cm) and widths of up to 2 feet (60 cm), although there are also compact varieties available. Ornamental kale is also susceptible to pests like aphids, whiteflies, and spider mites, and diseases like powdery mildew and root rot.
Nutritional Requirements
Like all plants, ornamental kale requires essential nutrients to grow and thrive.
