The plant is unequally distributed and prefers rocky limestone places at about 1800–3000 m altitude. It is non toxic, and has been used traditionally in folk medicine as a remedy against abdominal and respiratory diseases. The dense hair appears to be an adaptation to high altitudes, protecting the plant from cold, aridity and ultraviolet radiation. 

As a scarce short-lived flower found in remote mountain areas, the plant has been used as a symbol for alpinism, for rugged beauty and purity associated with the Alps, and as a national symbol especially of Austria and of Switzerland. There is a folklore associated with the edelweiss in which it is stated that giving this flower as a gift to a loved one is a promise of dedication.


The scientific name Leontopodium is a Latin adaptation of Greek leontopódion (λεοντοπόδιον) "lion's paw". The first scientific name for Leontopodium alpinum which was validly published according to the current binomial nomenclature is Gnaphalium alpinum in the first edition (1753) of Linnaeus's Species Plantarum.

Since 1822 (Cassini) Leontopodium has no longer been considered part of the Gnaphalium genus, but classified alongside it as a distinct genus within the Gnaphalieae tribe. In 2003, Leontopodium alpinum was re-classified as a subspecies of Leontopodium nivale. Thus, the alpine edelweiss is currently recognized as being divided into two subspecies, Leontopodium nivale subsp. alpinum (Cass.) Greuter and Leontopodium nivale subsp. nivale.
