Among the better known species in this genus include:
Cynara cardunculus is the cardoon, artichoke thistle, or wild artichoke. The stems of cultivated varieties are used as food around the Mediterranean. It is also the source of a coagulant used as an alternative to rennet in the manufacture of cheese, with the advantage that the cheese is then fully suitable for vegetarians; many southern European cheeses are traditionally made in this way. The more commonly eaten globe artichoke is usually considered to be an ancient cultigen of this plant. Cardoon is an invasive species in United States, Argentina, and Australia.
Cynara humilis is a wild thistle of southern Europe and north Africa which can be used in cheesemaking like C. cardunculus.
Cynara scolymus (syn. C. cardunculus var. scolymus) is the common edible globe artichoke. It differs from C. cardunculus in that the leaf lobes and inner bracts of involucre are less spiny.
Cynara species are used as food plants by the larvae of many lepidopterans, such as the artichoke plume moth (Platyptilia carduidactyla), a pest of artichoke crops.
C. cardunculus is being developed as a new bioenergy crop in the Mediterranean because of its high biomass and seed oil yields even under harsh conditions.
Cynara scolymus (syn. C. cardunculus var. scolymus) - artichoke - area of origins unclear but probably Mediterranean; widely cultivated and naturalized
