How to Care for a Silver Mound Plant

By Sonia Acone ; Updated September 21, 2017

The silver mound plant (Artemisia schmidtiana) is also called wormwood or mugwort. It is a low-growing perennial, hardy in USDA hardiness zones 3 to 7, with silvery gray foliage. Growing 1 foot high and just as wide, this airy plant is perfect for rock gardens or in front of taller plants. It prefers well-drained soil and is drought tolerant.

Choose a site with full sun and well-drained soil. Plant container-grown plants in either the spring or fall.

Dig a hole to accommodate the plant. If planting more than one, they should be spaced at least 1 foot apart. Place the plant in the hole and fill with soil and water.

Clip off excess branches or runners to retain its mound-like shape. In areas with high humidity, silver mounds may look unruly and flop over.

Cut the plant back with scissors or snips, leaving only a few inches of the plant visible in late fall or early spring. It will grow back into a nicely rounded shape.

Check to be sure the soil is especially well drained during the winter. Soggy soil could kill the plant.
