Hieracium paniculatum, Allegheny hawkweed,[2] is a North American plant species in the dandelion tribe within the sunflower family. It grows only in the eastern United States and eastern Canada, from Nova Scotia west to Ontario, Michigan, and Indiana south as far as Georgia.[3]

Hieracium paniculatum is an herb up to 90 cm (3.0 ft) tall, with leaves mostly on the stem with only a few in a rosette at the bottom. Leaves are up to 150 mm (5.9 in) long, sometimes with teeth on the edges. One stalk can sometimes produce as many as 50 flower heads in a flat-topped array. Each head has 8-30 yellow ray flowers but no disc flowers.[4]
