Common chicory (Cichorium intybus) is a somewhat woody, perennial herbaceous plant of the daisy family Asteraceae, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and food additive. In the 21st century, inulin, an extract from chicory root, has been used in food manufacturing as a sweetener and source of dietary fiber. When flowering, chicory has a tough, grooved, and more or less hairy stem. It can grow to 1.5 metres (4 ft 11 in) tall. The leaves are stalked, lanceolate and unlobed; they range from 10–32 cm (4–12+1⁄2 in) in length and 2–8 cm (3⁄4–3+1⁄4 in) wide. The flower heads are 3–4 cm (1+1⁄4–1+1⁄2 in) wide, and usually light purple or lavender; it has also been described as light blue, and rarely white or pink. Of the two rows of involucral bracts, the inner is longer and erect, the outer is shorter and spreading. It flowers from July until October.
