Cichorium is a genus of plants in the dandelion tribe within the sunflower family. The genus includes two cultivated species commonly known as chicory or endive, plus several wild species. Common chicory (Cichorium intybus) is a bushy perennial herb with blue or lavender (or, rarely, white or pink) flowers. It grows as a wild plant on roadsides in its native Europe, and in North America, where it has become naturalized. It is grown for its leaves, when it is known as leaf chicory, endive, radicchio, Belgian endive, French endive, or witloof. Other varieties are grown for their roots, which are used as a coffee substitute, similar to dandelion coffee.
