Common chicory (Cichorium intybus) is a bushy perennial herb with blue or lavener 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, or for the roots, which are baked, ground, and used as a coffee substitute and additive. Common chicory is also known as blue sailors, succory, and coffeeweed.
