Botanical Name

ARTEMISIA schmidtiana

Plant Common Name

Schmidt's Wormwood, Silvermound, Wormwood

General Description

Schmidt's wormwood, or silvermound, is an herbaceous perennial that originates from Japan. It forms a mounded carpet of very finely divided silver foliage, hence the common name silvermound. It has panicles of insignificant yellow flowers that appear in mid-summer. The cultivar 'Nana' is a nice selection with a more compact habit. One ornamental aggravation with this plant is its tendency to fall open in the middle and show its bare inner stems (not pretty). This is a very hardy perennial that is moderately drought tolerant and does best in sites with full sun and well drained soils. It makes a nice addition to any perennial border.
