Hieracium scabrum, rough hawkweed,[1] is a North American plant species in the dandelion tribe within the sunflower family. It is native to eastern and central Canada and the eastern and central United States from Nova Scotia west to Ontario, Minnesota, and Kansas south as far as Georgia and Oklahoma.[2]
Hieracium scabrum is an herb up to 60 cm (2.0 ft) tall with many hairs so that it feels rough to the touch. L leaves mostly on the stem with only a few at the bottom. Leaves are up to 120 mm (4.7 in) long. One stalk can produce 5-50 flower heads in a conical or flat-topped array. Each head has 30-60 yellow ray flowers but no disc flowers.[3]
