Symphyotrichum pilosum, commonly called the hairy white oldfield aster[1] or frost aster,[2] is an herbaceous plant in the aster family.
It is native to eastern North America, where it is found in Canada and the United States.[3] It is widespread and common throughout its range. Its natural habitat includes communities such as prairies, open woodlands, and outcrops. In general, it responds positively to disturbance, and is often seen occupying sunny, weedy habitats.[4][5]
Two varieties are recognized, although determining the best taxonomy for this group is difficult due to polyploidy and hybridization.[6] The two currently recognized varieties are:[7]
- S. pilosum var. pilosum - Widespread, and often weedy
- S. pilosum var. pringlei - Found on alvars, cedar glades, and sand dunes[4]
