Lactuca tatarica is an herb up to 60 cm (2 feet) tall, with a large taproot. Most of the leaves are near the base of the plant, larger than leaves farther up. Each flower head has about 20 blue or purple (rarely white) ray flowers but no disc flowers.[3]


Among the Zuni people of New Mexico in the southwestern United States, the dried root gum of L. tatarica var. pulchella has been used as chewing gum.[5]
