The "prickly silver from Plainpalais" is the name of this traditional Geneva variety. It probably originated around 200 years ago from a hybridization of the then "Cardon de Tours" variety. The fleshy leaf stems have strong spines. This makes the ‘Epineux argenté de Plainpalais’ more elaborate both in terms of culture and preparation. But it is considered to be the best culinary cardoon ever. Of the few regions in Europe that still produce cardoon, Geneva is the only one in which thorny cardoon is cultivated. "Cardon épineux genevois" is now a protected AOP label.
