Chaerophyllum bulbosum is a species of flowering plant in the carrot family known by several common names, including turnip-rooted chervil, tuberous-rooted chervil, bulbous chervil, and parsnip chervil. It is native to Europe and Western Asia. It was a popular vegetable in the 19th century. Now virtually forgotten in Britain and the United States, root chervil is still used in French cuisine, in soups or stews. Storage also allows the development of the root's flavor, which is reminiscent of chestnut. The root is prepared by boiling. * *
