Nearly one hundred percent of all artichokes grown commercially in the United States are grown in California.

A native of the Mediterranean, the artichoke is a perennial in the thistle group of the sunflower (Compositae) family. In full growth, the plant spreads to cover an area about six feet in diameter and reaches a height of three to four feet.

The "vegetable" that we eat is actually the plant's flower bud. If allowed to flower, the blossoms measure up to seven inches in diameter and are a beautiful violet-blue color.

Approximately 80% of the state's total acreage lies within Monterey County. The Board of Supervisors of Monterey County declared the artichoke to be "the Official Vegetable of Monterey" in 1986. The heart of the artichoke industry is located near Castroville in Monterey County and Castroville proudly proclaims itself to be "The Artichoke Center of the World" on a huge banner that spans the main street.

While California artichokes are available throughout the year, peak season is March through May and again to a smaller degree in October. They are an extremely labor-intensive crop as the harvesting is done entirely by hand; and, because artichokes on the same plant mature at different times, the same field will be harvested every seven days during peak season. Labor represents 40 to 60 percent of the growing costs.

The artichoke is fun to eat, and it's good for you. One 12-ounce artichoke is a good source of vitamin C, folate and potassium. It's low in sodium, fat-free and a dieter's delight at only 25 calories.
