About

Arctium is a genus of biennial plants commonly known as burdock, in the family Asteraceae. Native to Europe and Asia, several species have been widely introduced worldwide. Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of velcro.

Safety

The green, above-ground portions may cause contact dermatitis in individual with allergies as the plant contains lactones.

Where it grows
