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]

Uses

The leaves and young plants are edible when cooked.[15]
