Asters are keystone species in Virginia and the aromatic aster fulfills many niches because of its value to wildlife and fall beauty, allowing it to serve as a substitute for chrysanthemum.  The bluish purple daisy-like flowers top a bushy perennial that thrives in full sun and calcareus well-drained soils.  It is sometimes considered aggressive in a formal garden, spreading by self-seeding and stolons, but can be easily controlled.  New or young plants benefit from deer protection, but once established it is unnecessary.  
 
Direct sow, barely covering seed that will germinate in warm soil.  Also a good candidate for winter sowing technique but stratification not required.
