Chaerophyllum bulbosum

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. It is native to Europe and Western Asia. It was a popular vegetable in the 19th century.

This is a tall annual herb with fringelike divided leaves and large umbels of white flowers. The plant is cultivated on a small scale in parts of Europe for the edible tubers, which look like a dark gray carrot with yellowish-white flesh. After the harvest they are stored for a few months under cold conditions. During storage, sugar content increases through hydrolysis of starch by amylases.
