Eurybia surculosa
''Eurybia surculosa'', commonly known as the creeping aster, is an herbaceous perennial in the composite family that was previously treated in the genus ''Aster''. It is native to the eastern United States where it is found in sandy soils along the coastal plain, though when ''E. compacta'' is also present, it exists farther inland in the southern Appalachian mountains and the Cumberland Plateau. Although the species is not seriously threatened, it is locally endangered in Virginia and Alabama. The flowers, which have bluish violet ray florets and pale yellow disc florets that eventually turn purplish, emerge in summer and persist into the fall.
