Eurybia schreberi

Schreber’s Aster

Eurybia schreberi (Nees) Nees is native to damp to mesic deciduous (maple, elm, oak), mixed woods, thickets, shaded roadbanks from Ontario to southern Maine south to Alabama in many disjunct populations and in several disjunct areas in southeastern Wisconsin and northern Illinois (Brouillet 2006 FNA).  The species is distinguished by its large cylindrical involucres of appressed glandless linear oblong-lanceolate phyllaries and white ray florets.  It blooms generally earlier than E. macrophylla. It is similar to diploid E. divaricata and octoploid E. macrophylla. The species is hexaploid (2n=54). 

Eurybia schreberi is rare or extirpated in a many states at the northern limit of its range and introduced in Europe (Scotland; Brouillet 2006 FNA).
