Smallhead or Small White Aster
Symphyotrichum parviceps (E. S. Burgess) G. L. Nesom is native to open, dry, sandy, or loamy soils, open woods, barrens, prairies, fields, roadsides, old cemeteries in Ark., Ill., Iowa, Kans., Mo., and Okla. (Brouillet et al. 2006, FNA). The species includes diploids (2n=16), tetraploids (2n=32) and hexaploids (2n=48). The small head size of diploids and tetraploids makes the species distinctive, but the hexaploids can be confused with Symphyotrichum pilosum.
