The cardoon (Cynara cardunculus

Mediterranean region,[4]
where it was domesticated in ancient times and still occurs as a wild plant.

Description

The wild cardoon is a stout

capitulum up to 6 cm (2 in) in diameter.[5][6][7][8]

It is adapted to dry climates, native across a circum-

Mediterranean south (Gard, Hérault, Aude, Pyrénées-Orientales, Corsica).[7] It has become an invasive weed in the pampas of Argentina,[8] and is also considered a weed in Australia and California.[11][12][13][14]

The "giant thistle of the Pampas" reported by Charles Darwin has been identified as cardoon.[15]

Cultivation

Cultivated cardoon foliage, Madrid Royal Botanical Garden, without leaf spines.

The two main cultivar groups are the cardoon (Cynara cardunculus Cardoon Group, syn. C. cardunculus var. altilis DC), selected for edible leaf stems, and the artichoke (Cynara cardunculus Scolymus Group, sometimes distinguished as Cynara scolymus or C. cardunculus var. scolymus (L.) Fiori), selected for larger edible flower buds. They differ from the wild plant in being larger (up to 2 m tall), much less spiny, and with thicker leaf stems and larger flowers, all characteristics selected by humans for greater crop yield and easier harvest and processing.[5][16] Wild and cultivated cardoons and artichokes are very similar genetically, and are fully interfertile, but have only very limited ability to form hybrids with other species in the genus Cynara.[5]

The earliest description of the cardoon may come from the fourth-century BC Greek writer

colonial America, but fell from fashion in the late 19th century and is now very uncommon.[citation needed
]

In Europe, cardoon is still cultivated in

Huguenot refugees introduced it about 1685, the local cultivar Argenté de Genève ("Cardy")[17] is considered a culinary specialty. "Before cardoons are sent to table, the stalks or ribs are blanched tying them together and wrapping them round with straw, which is also tied up with cord, and left so for about three weeks".[18] Cardoons also are common vegetables in northern Africa, often used in Algerian or Tunisian couscous

Cardoon stalks can be covered with small, nearly invisible spines that can cause substantial pain if they become lodged in the skin. Several spineless cultivars have been developed to overcome this.

Cardoon requires a long, cool growing season (about five months), and while it is not particularly frost-sensitive, in heavier freezes it may lose its leaves and resprout, or in extended hard freezes, die. It also typically requires substantial growing space per plant, so is not much grown except where it is regionally popular.

In cultivation in the United Kingdom, this plant has gained the Royal Horticultural Society's Award of Garden Merit.[21][22]

Culinary

While the flower buds can be eaten much as small (and spiny)

braised in cooking liquid. Cardoon stems are part of Lyonnaise cuisine
(e.g. gratin de cardons). Only the innermost, white stalks are considered edible, and cardoons are therefore usually prepared for sale by protecting the leaf stalks from the sunlight for several weeks. This was traditionally done by burying the plant underground, thus, cardoon plantations in Spain are often formed by characteristic earth mounds surrounding each plant, the earth covering the stalks. In modern cultivation, the plant is usually instead wrapped in black plastic film or other opaque material.

The flower buds of wild cardoons are still widely collected and used in southern

Serra da Estrela
cheeses in Portugal. Cardoons were also said to have been used by the Romani or "gypsies" and this would make sense as their encampments would often be situated near sources of water. The vegetable was free for the picking, and could account for the widespread use of the plant. That part is speculative.

Cardoon leaf stalks, which look like giant celery stalks, can be served steamed or braised, and have an artichoke-like flavor with a hint of bitterness. They are harvested in winter and spring, being best just before the plant flowers.[16] In the Abruzzo region of Italy, Christmas lunch is traditionally started with a soup of cardoon cooked in chicken broth with little meatballs (lamb or, more rarely, beef), sometimes with the further addition of egg (which scrambles in the hot soup – called stracciatella) or fried chopped liver and heart.[24]

The cardoon stalks are considered a delicacy in

beans
as well.

Because of their seasonality (from November to February), cardoons are a staple of the Christmas dinner in Navarre and the surrounding regions; for the same reason, cardoons are often sold as vegetable preserves, usually in water or brine, so that they can be eaten all year round.[25] Cardoons are an ingredient in one of the national dishes of Spain, the cocido madrileño, a slow-cooking, one-pot, meat and vegetable dish simmered in broth.

In Crete, cardoons are eaten raw, with a drizzle of lemon juice, as a meze, and are considered an excellent accompaniment for raki.[26]

In the US, it is rarely found in conventional grocery stores but is available in supermarkets that cater to largely Italian and European neighborhoods in the mid Atlantic states, as well as some

St. Joseph's altars
in New Orleans.

Cardoons can also be found in their "wild" state, on the banks of streams and rivers, and even drainage ditches on the sides of roads in rural areas. These plants look little like the cultivated variety found in stores. They have many thin stems with broad broad leaves at their ends. There is a reddish color on the stems which grow tough, hollow and inedible as they age. The wild ones are picked in the spring and early summer. To use them, the leafy part should be removed, and the stems cleaned of "stringy" fibers. This cleansing will stain the hands black, and so many people didn't want to prepare them (Source: Sicilian grandmothers born in Italy in the 1890's).[citation needed]

Cardoon is one of the herbs used to flavour Amaro liqueur, which may be called Cardamaro.

Other uses

Cardoons are used as a vegetarian source of

Serra da Estrela and Nisa
.

The cardoon is also grown as an ornamental plant for its imposing architectural appearance, with very bright silvery-grey foliage and large flowers in selected cultivars.[8]

Cardoon has attracted recent attention as a possible source of

bioplastics
