Crepis biennis is a European species of flowering plant in the daisy family with the common name Rough Hawksbeard.^[1] It is native to Europe and Asia Minor, as well as being sparingly naturalized in scattered locations in the northeastern United States and on the island of Newfoundland in eastern Canada.^[2]^[3]^[4] Many people think that they are dandelions because they look so alike but that is only because both are in the daisy family.

Crepis biennis is a perennial herb up to 120 cm (48 inches) tall. One plant can produce as many as 14 small flower heads, each with up to 100 yellow ray florets but no disc florets.^[1]
