Anaphalis margaretacea was widely planted as an ornamental and escaped. It apparently naturalized from its native range in both Asia and North America; it is cultivated and naturalized in Europe.
Anaphalis margaritacea has the aspect of Pseudognaphalium; it differs in being subdioecious (polygamo-dioecious; the heads either staminate or primarily pistillate) and in its distinctive cypselar vestiture. It is further recognized by its combination of rhizomatous habit, subclasping-decurrent, bicolor, revolute leaves, and distally white phyllaries. Segregate species and varieties have been described among the North American plants (in addition to the two cited above), based on variation in habit, vestiture, and leaf morphology and density, but the variants appear to be more like a complex series of ecotypes rather than broader evolutionary entities.

Brief Summary
provided by EOL authors
Anaphalis margaritacea is a wildflower of broad world distribution in bicoastal North America and Asia, as well as an alien species in Europe. Typical habitats are woodlands, roadsides and other disturbed places at elevations below 3200 meters.
Known by the common name of Western pearly everlasting, this slender stemmed wildflower attains a height of 20 to 120 centimeters. The sessile, linear to lanceolate leaves are three to ten centimeters long. The leaves are entire, with green or gray above, and white-tomentose on the lower leaf surface. The flower color is pearl white.

Anaphalis margaritacea

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.
Description
A. margaritacea grows erect up to about 90 centimetres (3 feet) tall,[6] with narrow, alternate leaves up to 12.5 cm (5 inches). The undersides of the leaves are densely covered in tiny hairs.[7] The stems are dry and brittle. The whitish to yellowish flower grows to about 6 millimetres (1⁄4 in) across[7] as part of a corymb inflorescence, the most conspicuous part of which is the numerous pearly white bracts that surround the disc florets.[8] It blooms between June and September.[7]
The plant is dioecious, meaning the pollen-producing (male) and seed-producing (female) flowers are borne on separate plants.[7]

Etymology
The species' common name 'pearly everlasting'[9] comes from the pearly white bracts.[10]
Distribution and habitat
It is widespread across most of Canada and the United States, as well as northwestern Mexico.[8][11] Asian populations are found in China, the Russian Far East, Japan, Korea, northern Indochina, and the Himalayas.[12] The species is reportedly naturalized in Europe though not native there. It prefers dry, sunny climates, but is hardy to temperatures well below freezing.[7]
Ecology
The leaves are host to the caterpillars of the American painted lady butterfly (Vanessa virginiensis)[13] and the painted lady butterfly (Vanessa cardui).[14]
Cultivation
Western pearly everlasting is sometimes grown by gardeners for its attractive foliage and modestly beautiful white blooms.[15] They prefer a well drained soil, somewhat sandy and dry and with less organic matter. At least part sun conditions, if not full sun, are required for them to grow successfully. They can become somewhat aggressive spreaders in optimal conditions.[16]
Uses
The flowering stems of western pearly everlasting can be dried and the fluffy flower heads are used in dried flower arrangements.[16] The leaves and young plants are edible when cooked.[17]
