Understanding Kale: Basic Classification
Kale, known scientifically as Brassica oleracea, is a leafy green vegetable. It belongs to the Brassicaceae family. Kale is related to cabbage, broccoli, and cauliflower. Its unique characteristics make it a versatile plant.
Taxonomical Classification of Kale

- Kingdom: Plantae
- Division: Angiosperma
- Class: Dicotyledonae
- Order: Brassicales
- Family: Brassicaceae

Plant Structure and Growth Pattern
Kale plants are biennials, living for two years. In the first year, they grow leaves and a strong stem. The second year, they bloom and produce seeds before dying.
Kale can grow up to 1 meter tall. Its leaves are green or purple and don’t form a tight head like other Brassica vegetables.
Botanical Characteristics
Kale leaves can be curly or smooth. They grow from a central stem. The plant can handle cold temperatures, even as low as -15°C (5°F).
Kale is grown from seed and does well in various soils. It needs good drainage.
“Kale originated in the eastern Mediterranean and Anatolia, where it was cultivated for food beginning by 2000 BCE at the latest.”
Kale Is Vegetable or Fruit: The Definitive Answer
Kale is clearly a vegetable, not a fruit. Vegetables are parts of plants we eat, like leaves, stems, roots, or flowers. Kale’s leaves are full of nutrients and fiber, making them a great example of a plant’s vegetative part.
Fruits grow from the ovary of plants and have seeds. Kale leaves, however, are not seeds. They are part of the plant’s vegetative structure. Kale is grouped with other dark-green veggies like broccoli and spinach, all classified as vegetables.
Kale is also a leafy green, like arugula and lettuce. While we don’t have exact numbers on kale’s popularity, it’s definitely seen as a vegetable. This classification is clear and consistent.
“Kale ‘Rainbow Candy Crush’ was shortlisted for RHS Plant of the Year 2021, further underscoring its status as a prized vegetable.”
So, when you enjoy kale in a salad or in your cooking, you’re eating a healthy vegetable. Kale’s nutritional value and health benefits make it a top choice among veggies.
