Leontopodium nivale, commonly called edelweiss, is a mountain flower belonging to the daisy or sunflower family Asteraceae. The plant prefers rocky limestone places at about 1,800–3,400 metres (5,900–11,200 ft) altitude. It is a non-toxic plant. 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 of several countries, specifically Bulgaria, Austria, Slovenia, Switzerland, and Italy. In Romania it was declared a "monument of nature" in 1931. The Edelweiss day is celebrated on 5 March. According to folk tradition, giving this flower to a loved one is a promise of dedication.
