The slightly bitter vegetable with the Latin name Cichorium intybus was first grown near Brussels in the 1840s by trimming the leaves and forcing the roots to produce pale white-and-yellow chicons in the darkness of the soil.
Chicory prefers a light well dug soil which is reasonably fertile but it is tolerant of poor soil. It can be grown in full sun or partial shade. It's a good crop for growing between rows of peas and sweet corn. At the beginning of the season the chicory will get full sun. As the season progresses the growing peas / sweet corn will shade the chicory from the full sun.
