Hieracium megacephalum, the coastal plain hawkweed or bigheaded hawkweed,[4] is a North American plant species in the tribe Cichorieae within the family Asteraceae. It grows only in the southeastern United States, in Georgia, Florida, and the Carolinas.[5]

Hieracium megacephalum is an herb up to 40 cm (16 in) tall, with leaves on the stem and also in a rosette at the bottom. Leaves are up to 120 mm (4.7 in) long, sometimes with teeth on the edges. One stalk can produce as many as 50 flower heads in a flat-topped array. Each head has 20–50 yellow ray flowers but no disc flowers.[6]
