Artichoke

life science Maturity 7-9 Next article →

The artichoke (Cynara cardunculus var. scolymus) is a cultivated variety of a thistle species.

It is grown specifically for its edible flower buds. These buds are harvested before the flowers fully bloom. Once the flowers bloom, the structure becomes coarse and barely edible. This vegetable is a domesticated version of the wild cardoon, a perennial plant native to the Mediterranean region. Artichokes are important both as a food source and as an ornamental plant due to their large, purple flower heads.

To understand the artichoke, one must look at the anatomy of the bud. The flower-head is actually an inflorescence, which is a cluster of many small budding flowers. This cluster is surrounded by many bracts, which are leaf-like structures. The edible portions consist of the fleshy lower parts of these involucral bracts. At the very bottom of the bud is the base, commonly called the heart.

In the center of the bud lies a mass of immature florets. This central part is known as the choke or the beard. In older or larger flowers, the choke becomes inedible. The plant itself grows tall with long, silvery, glaucous-green leaves that have deep lobes.

There are many different types of artichokes categorized by their appearance and how they are grown. Some varieties are classified by color, such as green or purple types. For example, 'Green Globe' is a large green variety grown in the USA and South Africa. 'Romanesco' is a large purple variety from Italy. Other types are distinguished by having spines, such as the 'Spinoso Sardo e Ingauno' from Sardinia.

Cultivators also group them by how they are propagated. Some are grown through vegetative means like root cuttings or division. Others are bred specifically for seed propagation, such as the 'Imperial Star' cultivar.

The history of the artichoke is deeply connected to Mediterranean civilizations. The wild cardoon was mentioned by Homer and Hesiod in the eighth century BCE. Ancient Greeks called them kaktos and ate the leaves and flower heads. The Romans referred to the vegetable as carduus, which is where the name cardoon comes from.

Evidence of cultivated artichoke seeds was found during excavations of Roman-period Mons Claudianus in Egypt. In the sixteenth century, the English word 'artichoke' was borrowed from northern Italian. This Italian term likely came from Spanish or directly from medieval Andalusi Arabic. The Arabic root refers to "scale."

Artichoke cultivation has moved across the globe over many centuries. In 1530, the Dutch introduced the plant to England, where it grew in King Henry VIII's garden. By the mid-17th century, artichoke hearts were considered luxury ingredients in European courts. In the nineteenth century, they reached the United States via French and Spanish immigrants. Today, global production is massive. In 2020, the world produced approximately 1,516,955 tonnes of artichokes.

Italy was the top producer with 367,080 tonnes, followed by Egypt with 308,844 tonnes and Spain with 196,970 tonnes.

In the United States, the industry is highly concentrated. California provides nearly 100% of the American crop. About 80% of that production occurs in Monterey County. The town of Castroville is so famous for this that it calls itself "The Artichoke Center of the World." This area even hosts an annual Artichoke Festival. While most artichokes are perennials that produce edible flowers in their second year, some new cultivars change this cycle. The 'Imperial Star' is bred to produce a harvest in just the first year. The 'Northern Star' variety is even more hardy and can survive subzero temperatures.

Beyond their history, artichokes are nutritionally significant. A cooked, unsalted artichoke is composed of 82% water, 12% carbohydrates, 3% protein, and 3% fat. They are a rich source of folate, providing 20% or more of the Daily Value. They also provide moderate amounts of vitamin K, copper, and magnesium. When preparing them, chefs often simmer the buds for 15 to 30 minutes or steam them for up to 40 minutes. Because they contain enzymes, cut artichokes can turn brown through oxidation, so they are often placed in acidified water to stay fresh.
