Chaerophyllum bulbosum is a species of flowering plant from the carrot family and known by several common names, including turnip-rooted chervil, tuberous-rooted chervil, bulbous chervil, and parsnip chervil. Chaerophyllum bulbosum is a biennial plant. In the first year, its rosette of leaves produces large amounts of starch, which are stored in the taproot to provide energy for the plant to flower in the second year. In the second year, it grows up to a height of 70 cm to > 2 m.
