Eurybia surculosa

Creeping Aster

Eurybia surculosa (Michx.) G.L. Nesom is native to sandy and gravelly soils in the central and southern Appalachian Mts. from Ohio western Virginia south to Georgia and in a small disjunct area on the coastal plain in South Carolina and Georgia (Brouillet 206 FNA).  The species is distinguished from similar species by its herbacous rhizomes that become woody, slender and scaly, involucres 7-11(-13) mm, 35-65 phyllaries, 13-30 violet rays, and 25-40 discs with tubes shorter than the throats.  It can be confused with E. compacta, its close relative from the coastal plains.  Its larger heads help to differentiate it from E. compacta.  The species is tetraploid (2n=36).

Eurybia surculosa is of conservation concern in Virginia and Alabama. It is often confused with E. compacta, its close relative from the coastal plains (Brouillet 206 FNA).
