Alphabetical list

Symphyotrichum pilosum (formerly Aster pilosus), commonly called hairy white oldfield aster[5] or frost aster,[6] is a flowering plant in the family Asteraceae native to central and eastern North America. It is a perennial, herbaceous plant that may reach 20 to 120 centimeters (8 to 47 inches) tall. Its flowers have white ray florets and yellow disk florets.[7]

Distribution and habitat[]

It is native to central and eastern North America, where it is found in Canada and the United States.[7] 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.[8][9]

Taxonomy[]

Two varieties are recognized, although determining the best taxonomy for this group is difficult due to polyploidy and hybridization.[10] The two currently recognized varieties are as follows:[7]

  • S. pilosum var. pilosum — stems and leaves hairy, widespread and often weedy
  • S. pilosum var. pringlei — commonly called Pringle's aster;[4] stems and leaves mostly smooth, found on alvars, cedar glades, and sand dunes[8]

Cultivation[]

Symphyotrichum pilosum var. pringlei[11] and its cultivar 'Ochtendgloren'[12] have both won the Royal Horticultural Society's Award of Garden Merit.[13]
