Cynara

Cynara is a genus of thistle-like perennial plants in the family Asteraceae. They are native to the Mediterranean region, the Middle East, northwestern Africa, and the Canary Islands. The genus name comes from the Greek kynara, which means "artichoke". 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......read more on Wikipedia.
