Pilosella flagellaris (synonym Hieracium flagellare[1]) is a European plant species in the dandelion tribe within the sunflower family. It is native to Europe but naturalized in scattered locations in the United States and Canada.[1][2]

Pilosella flagellaris is a small herb up to 20 cm (7.9 in) tall, with leaves mostly in a rosette at the bottom. Leaves are up to 130 mm (5.1 in) long, with no teeth on the edges. One stalk will produce 2-4 flower heads in a flat-topped array. Each head has 90–120 yellow ray flowers but no disc flowers.[3]
