Anaphalis margaritacea, commonly known as the western pearly everlasting or pearly everlasting, is an Asian and North American species of flowering perennial plant in the sunflower family. It is widespread across most of the United States and Canada, as well as northwestern Mexico. Asian populations are found in China, the Russian Far East, Japan, Korea, northern Indochina, and the Himalayas. The species is reportedly naturalized in Europe though not native there. The leaves are host to the caterpillars of the American painted lady butterfly (Vanessa virginiensis).
