Phenology: Flowering early summer.
Habitat: Open to semishaded, mesic to dry, rocky, gravelly or silty, often calcareous areas, alpine tundra, montane to alpine meadows, cold prairies, Artemisia steppes, gravelly or eroding stream banks and flats, edges of open riparian boreal forests, bluffs, talus and cliffs, sandy ridges in muskeg
Elevation: 10–3700 m
Alta., B.C., N.W.T., Ont., Yukon, Alaska, Colo., Idaho, Wyo., e Asia (Russian Far East, e Siberia).
Aster alpinus is the only species of the genus in the strict sense that is native to North America. The report of the species for Quebec on the NatureServe website is erroneous. The species is thought to be rare in Ontario, Colorado, Idaho, and Wyoming. The reports for Idaho and Wyoming are new. Confusion in identification often occurs with Erigeron caespitosus Nuttall, E. glacialis Nuttall, and E. hyperboreus, among others. J. C. Semple et al. (2002) used the name A. culminis for the North American entity; my study of Russian and North American material showed that it is not possible to distinguish between Siberian and North American materials, which indeed share a pubescence type different from that of the typical subspecies. It is not possible to divide the species easily into distinct species or varieties. The only difference found in material from the two areas is that rays in the former tend to be purple, while in the latter they are mostly pinkish white to pink, sometimes purple, a difference deemed insufficient at the present time to warrant species recognition. A thorough biosystematic and molecular study of the complex may resolve this taxonomic problem.
Aster americanus Onno, referable here, is an invalid name.
