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.

Planning Your Garden With Broccoli

As you plan your garden, it's important to think about the spacing, size, light, and nutrient requirements of all of your plant and how they'll grow together.

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.

By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.
