Blue-flowered perennial plant (Cichorium intybus) of the aster family (Asteraceae). Native to Europe, it was introduced to the U.S. late in the 19th century. Chicory has a long, fleshy taproot; a rigid, branching, hairy stem; and lobed, toothed leaves, similar in appearance to dandelion leaves, around the base. Both roots and leaves are edible. The roots are used as a flavouring in or substitute for coffee. The plant is also grown as a fodder or herbage crop for cattle.
