Broccoli is a cultivar of the species Brassica oleracea, or wild cabbage, whose flowering head is consumed in many food cultures across the world. Wild cabbage originated along the coast of the Mediterranean and was domesticated at least 2,000 years ago. This domesticated cabbage was bred over time to create several different cultivars including cauliflower, kale, kohlrabi, and Brussels sprouts.
Broccoli was first popularized in Italy before spreading to dinner tables in France, England, and eventually the United States. It wasn’t commercially grown in the U.S. until the 1920s. Like other brassicas, broccoli thrives in cooler weather. In the greater Prescott area, it’s planted in early winter for harvest in late April through early July, depending on temperatures. It’s also often planted in late summer to harvest in early fall. Broccoli is susceptible to cabbageworms and infestations of aphids, making it a more challenging crop for the beginning gardener.
There are three common varieties of broccoli: Calabrese, Sprouting, and Romanesco. Calabrese is the variety most commonly found in grocery stores, with large crowns and thick stalks. Sprouting broccoli has more but smaller crowns and thinner stalks. And Romanesco is a beautiful variety of broccoli with yellow-green cone-shaped florets.
Broccoli is an excellent source of dietary fiber, vitamins A, C, K, and B6, as well as folate, potassium and manganese. It’s also a good source of iron, zinc, and calcium. Broccoli stores well in the refrigerator and can often keep for a couple of weeks there. It is delicious on its own — steamed, roasted, fried, baked, or sautéed. It’s a versatile vegetable that is great in stir-fries, soups, pasta dishes, and more. For a new twist, try it as a pesto in place of basil.
