Anaphalis margaritacea, commonly known as the western pearly everlasting[5] or pearly everlasting, is an Asian and North American species of flowering perennial plant in the family Asteraceae.

A. margaritacea grows erect up to about 90 centimetres (3 feet) tall,[6] with narrow, alternate leaves up to 12.5 cm (5 inches).

[8][11] Asian populations are found in China, the Russian Far East, Japan, Korea, northern Indochina, and the Himalayas.

[7][additional citation(s) needed] The leaves are host to the caterpillars of the American painted lady butterfly (Vanessa virginiensis)[13] and the painted lady butterfly (Vanessa cardui).

[14] Western pearly everlasting is sometimes grown by gardeners for its attractive foliage and modestly beautiful white blooms.
