Aster alpinus (Alpine aster) Aka Aster Species, Alpine Aster, or Wild Aster, is an ornamental plant native to the mountains of Europe (including the Alps), with a subspecies native to Canada and the United States. It is a perennial forb (a forb is a herbaceous flowering plant that is not a graminoid and its name is derived from Greek (phorbḗ) meaning “pasture” or “fodder”(grasses, sedges and rushes)). The plant belongs to the genus Aster, and the Asteraceae family.
‘Aster’ comes from Latin ‘astrum’, meaning star. ‘Alpinus’ and alpine refers to the Alps, an European mountain range, although Aster Alpinus is also North American. USDA hardiness zones are from 3-8, as it does better in generally cooler climates. In Canadian provinces, towards eastern North America, the species is critically imperiled. However, in both Canadian provinces and US states, at north-western and southern parts, the species is apparently secure (see USDA map in the link below).
(Shot at f/2.8) There is Aster amellus (European Michaelmas-daisy, Italian Aster) which is the largest (7.9–19.7 in), and is considered European and Asian, and the one shown here, the Aster alpinus (Alpine aster), which is both European and North American, growing to about 6–12 inches.
