About Euthamia caroliniana (L.) Greene ex Porter & Britton
Euthamia caroliniana, commonly called Carolina goldentop, grows up to 1 meter (3 ft 3 in) tall from a branched, creeping rhizome. Along the east coast, the only species with a similar appearance is grass-leaved goldentop. Grass-leaved goldentop has wider leaves with one to three conspicuous veins, while Carolina goldentop has narrow leaves with only one vein. The range of Euthamia caroliniana overlaps with that of Great Plains goldentop in the western Great Lakes and along the Gulf Coast, and with bushy goldentop along the Gulf Coast. Euthamia caroliniana is found primarily on the Atlantic Coastal Plain, between Nova Scotia and eastern Texas. It also has established populations in the Great Lakes region and around Lake Champlain. Inland populations are also recorded from Indiana to Kentucky. Within its range, it occurs in open sandy areas, such as powerline cuts in pine barrens. E. caroliniana grows in a range of additional habitats, including moist forests, pastures, roadsides, ditches, and other disturbed areas. It forms a persistent soil seed bank that can survive through fire disturbance.
