Broccoli is a cool-season vegetable that is a member of the cabbage family. It is an annual plant that grows best in full sun and well-drained soil. Broccoli plants have dark green leaves and thick, edible stems. The edible part of the plant is the flower head, which consists of small buds that can range from deep green to purplish-green in color. The flower head is usually harvested when it is tight and compact, before the buds begin to open. Broccoli is a nutritious vegetable that is high in vitamins A, C, and K, as well as dietary fiber.
