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.[2][3][4] It can live in communities dominated by post oak as well.[2]


S. patens has been observed flowering in January, March through May, October, and November and fruiting between October and November.[3][5]

Fire ecology

Burton (2009) found that the percent cover of S. patens showed a positive linear response to increased fire frequency.[2]
