 "Eurybia paludosa" is often confused with the closely related "Eurybia hemispherica".Despite the fact that both of these asters are found in the southeastern United States, they do not occur in the same geographical regions nor the same habitats.For example, in North Carolina, where both plants are present "E. paludosa" occurs along the coastal plain, but "E. hemispherica" is confined to the mountains.
