Okay, I looked at the wikipedia page. So chicory is the genus.
Chicorium endivia - that's 'cultivated endive' or curly endive and escarole
Chicorium intybus - that's 'common chicory' or radicchio, belgian endive, witloof
Chicorium pumilum - that's 'wild endive' which I think would just be considered a forage?
Okay, so which one of these chicories are you looking for?
I don;t know if I am more or less confused now!
