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.
