A description of Symphyotrichum patens is provided in The Flora of North America.
This species can live in humid, subtropical climates in drying sandy loam on the edges of woodland remnants, shade of mesic woodlands, xeric limestone prairies, open old-field pine woods, and sandy clay of the Red Hills.    It can live in communities dominated by post oak as well.  This species is also found in disturbed habitats such as upland pine-hardwoods, partially wooded vacant lots, and beside trail edges.  Associated species include Pinus echinata, Schoenus nigricans, Solidago odora, Callicarpa americana, Myrica cerifera, Liquiambar styraciflua, and Rhus copallinum. 
Burton found that the percent cover of S. patens showed a positive linear response to increased fire frequency.
