Alpine aster (Aster alpinus)

Dmitry Poltavsky - Aster alpinus

Alpine aster is an ornamental plant native to the mountains of Europe (including the Alps and the Pyrenees), a subspecies native to Canada and the United States. This is a perennial forb, has purple, pink or blue flowers, belonging to the Aster family. The genus name comes from the Latin word Aster for star shaped flowers. The specific epithet means Alpine; from the high mountains above the timberline. This species is very variable. The typical variety appears to be European and does not reach Siberia; specimens identified as A. alpinus var. alpinus in China belong to A. alpinus var. vierhapperi, the variety widespread from Siberia to North America.
