Asteraceae

Botanical Name

ARTEMISIA ludoviciana

Plant Common Name

Western Mugwort, White Sagebrush

General Description

Western mugwort is a clump-forming, herbaceous perennial native to western North America, including Mexico. The lance shaped, silvery white leaves, become greener with age and bear insignificant, woolly, yellowish brown flowerheads from midsummer to fall.

Western mugwort is often regarded as invasive and grows best in well drained soil and full sun. This plant is used in sunny mixed borders and rock gardens. Cultivars of note include 'Silver King' which is compact and has leaves that turn reddish in autumn, and 'Silver Queen' with larger leaves and does not produce as many of the dreary looking flowers. 'Valerie Finnis' is also a shorter growing cultivar with silver leaves that are lobed.
