About

Symphyotrichum () is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family, Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as one species in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster (Symphyotrichum novae-angliae) and New York aster (Symphyotrichum novi-belgii).

Where it grows

As a whole, Symphyotrichum is native throughout the Americas, with one species, S. ciliatum, also native to eastern Eurasia. Several species have been introduced to Europe and other parts of the world. Most species are native to Mexico, the United States, and Canada, with several species occurring in the West Indies and Central America. Most members of subgenus Astropolium are restricted to South America.
