early sixteenth centuries, when the artichoke appeared as a new arrival with a new name, which may be taken to indicate an arrival of an improved cultivated variety: The Dutch introduced artichokes to England, where they grew in Henry VIII's garden at Newhall in 1530. From the mid-17th century artichokes 'enjoyed a vogue' in European courts. The hearts were considered luxury ingredients in the new court cookery as recorded by writers such as François Pierre La Varenne, the author of Le Cuisinier François (1651). It was also claimed, in this period, that artichokes had aphrodisiac properties. They were taken to the United States in the nineteenth century—to Louisiana by French immigrants and to California by Spanish immigrants. Agricultural output Cultivation of the globe artichoke is concentrated in the Americas and the countries bordering the Mediterranean basin. The main European producers are Italy, Spain, and France and the main American producers are Argentina, Peru and the United States. In the United States, California provides nearly 100% of the U.S. crop, with about 80% of that being grown in Monterey County; there, Castroville proclaims itself to be "The Artichoke Center of the World" and holds the annual Castroville Artichoke Festival. More recently, artichokes have been grown in South Africa in a small town called Parys, located along the Vaal River. In 2020, the world produced approximately 1.5 million tons of artichokes. Artichokes can be produced from seeds or from vegetative means such as division, root cuttings, or micropropagation. Although technically perennials that normally produce the edible flower during only the second and subsequent years, certain varieties of artichokes can be grown from seed as annuals, producing a limited harvest at the end of the first growing season, even in regions where the plants are not normally winter-hardy. This means home gardeners in northern regions can attempt to produce a crop without the need to overwinter plants with special treatment or protection. The seed cultivar 'Imperial Star' has been bred to produce in the first year without such measures. An even newer cultivar, 'Northern Star', is said to be able to overwinter in more northerly climates, and readily survives subzero temperatures. Commercial culture is limited to warm areas in USDA hardiness zone 7 and above. It requires good soil, regular watering and feeding, and frost protection in winter. Rooted suckers can be planted each year, so mature specimens can be disposed of after
