Cichorium intybus.
Radicchio came to prominence with the pasta craze. It is a wild Italian chicory, related to the root chicories, and is enjoyed for its slightly bitter leaves. Red heads with white accents make radicchio an eye-catching crop. Chioggia types form rounded heads. Treviso radicchio looks like romaine lettuce, but it has pink-to-red leaves. The distinctive bitter taste is due to intybin which stimulates the appetite and digestive system. Radicchio’s bitterness mellows in cool conditions and its flavour is similar to that of escarole and Belgian endive. The key to growing radicchio is never allowing the soil to dry out, because moisture stress leads to bitter flavour.
