Arctium is a genus of biennial plants commonly known as burdock, family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Plants of the genus Arctium have dark green leaves that can grow up to 70 cm (28 in) long. They are generally large, coarse and ovate, with the lower ones being heart-shaped.
The taproot of young burdock plants can be harvested and eaten as a root vegetable. While generally out of favour in modern European cuisine, it is popular in East Asia.
