(''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. Wild and cultivated cardoons and artichokes are very similar genetically, and are fully interfertile, but only have very limited ability to form hybrids with other species in the genus ''Cynara''.
The earliest description of the cardoon may come from the fourth-century BC Greek writer

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.

(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.

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