Leontopodium nivale, commonly called edelweiss (German: Alpen-Edelweiß, English pronunciation (listen)), is a mountain flower belonging to the daisy or sunflower family Asteraceae. The plant prefers rocky limestone places at about 1,800–3,000 metres (5,900–9,800 ft) altitude. It is non-toxic and has been used in traditional medicine as a remedy against abdominal and respiratory diseases. Its leaves and flowers are covered with dense hairs, which appear to protect the plant from cold, aridity, and ultraviolet radiation. It is a scarce, short-lived flower found in remote mountain areas and has been used as a symbol for alpinism, for rugged beauty and purity associated with the Alps and Carpathians. It is a national symbol, especially of Romania, Austria, Slovenia, Switzerland, and Italy. According to folk tradition, giving this flower to a loved one is a promise of dedication.
