Cultivated cardoon leaf, Madrid Royal Botanical Garden, without leaf spines. The two chief cultivar groups are the cardoon ( Cynara cardunculus Cardoon Group, syn. C. cardunculus volt-ampere. altilis DC ), selected for comestible leaf stems, and the artichoke ( Cynara cardunculus Scolymus Group, sometimes distinguished as Cynara scolymus or C. cardunculus volt-ampere. scolymus ( L. ) Fiori ), selected for larger comestible flower buds. They differ from the wild plant in being larger ( up to 2 m grandiloquent ), a lot less barbed, and with thick leaf stems and larger flowers, all characteristics selected by humans for greater crop give and easier harvest and processing. [ 2 ] [ 12 ] Wild and cultivated cardoons and artichokes are very alike genetically, and are fully interfertile, but only have identical limit ability to form hybrids with other species in the genus Cynara. [ 2 ] The earliest description of the cardoon may come from the fourth-century BC Greek writer Theophrastus, under the diagnose κάκτος ( Latin : cactus ), although the claim identity of this plant is unsealed.

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 gallop intemperate freezes, die. It besides typically requires significant growing space per plant, sol is not much grow except where it is regionally popular.

This was traditionally done by burying the plant belowground, therefore, cardoon plantations in Spain are often formed by characteristic land mounds surrounding each plant, the worldly concern covering the stalks. In modern cultivation, the establish is normally rather wrapped in black formative film or other opaque material. The bloom bud of angry cardoons are still widely collected and used in southern Italy and Sicily. [ 17 ] In Spain and Portugal, the bloom bud are besides employed in cheesemaking : the pistils of the cardoon flower are used as a vegetable rennet in the make of some cheeses such as the Torta del Casar and the Torta de la Serena cheeses in Spain, or the Queijo de Nisa and Serra da Estrela cheeses in Portugal.
