There are lots of other chicories that are enjoyed in Italy and elsewhere, with a number of different species being eaten as a salad herb or vegetable.
I sowed a red-stemmed Catalogna chicory in early spring this year which has flourished. Radicchio, which has tall and heading varieties, are largely subspecies of Chicorium intybus.
