Taxonomy
Symphyotrichum puniceum is a variable species, and many forms have been named.[9] As of July 2021[update], Plants of the World Online (POWO) accepts one variety in addition to the autonym.[2] S. puniceum var. scabricaule occurs in the southern United States from Texas to Alabama.[10] The autonym, S. puniceum var. puniceum, occurs in most of the eastern United States and southern Canada.[11]
The species Symphyotrichum firmum is sometimes considered a variety of S. puniceum, but POWO and Flora of North America treat them as distinct species.[2][8] In 1999, Calvin College botanists David P. Warners and Daniel C. Laughlin gave evidence that they should be considered two distinct species.[12] Compared to S. firmum, Symphyotrichum puniceum is typically hairier, with purpler flowers, and does not form dense colonies but rather small clusters or scattered individuals.[13]

Hybrids between this species and Symphyotrichum boreale have been recorded and are called Symphyotrichum × longulum.[14]

Conservation
As of July 2021[update], NatureServe listed Symphyotrichum puniceum as Secure (G5) worldwide and Critically Imperiled (S1) in Mississippi.[1] It listed S. puniceum var. puniceum as Vulnerable (S3) in Kentucky,[15] and S. puniceum var. scabricaule as overall an Imperiled Variety (T2) and Critically Imperiled (S1) in Texas.[16]
Uses
Symphyotrichum puniceum has been used for medicinal purposes among indigenous people in North America. It has been documented that the Chippewa have smoked the root with tobacco to attract game.[17] Multiple uses have been reported for the Woodland Cree, including as an aid for tooth pain[18] and for healing a woman after childbirth.[19] The Iroquois have used the roots for healing of various ailments including colds,[20] fevers,[21] pneumonia,[22] typhoid,[23] and tuberculosis.[24]
