Powis Castle Artemisia (Artemisia 'Powis Castle') beautiful drought tolerant woody perennial valued for its finely dissected, aromatic, silver-gray foliage. It is evergreen down to 0 degrees F, if colder than -5degrees F, woody growth dies back too. Flowering is non-existant. As a perfect companion to vibrant flowering plants and ornamental grasses, it adds unique contrasting color and texture to waterwise landscapes. Most artemisias are best grown in poor to moderately fertile, dry to medium moisture, well-drained soils in full sun. In order to avoid occasional winter-kill in Kansas landscapes, it is advisable to plant on a south, east or west side of house or on south facing slopes or berms. Excellent soil drainage is essential for growing this plant well as poor lanky growth and root rot will occur in moist to wet soils. Tolerant of part-shade if kept dry. Cut back to 3-6" in early spring after dried winter silvery foliage stops looking attractive. New growth will emerge from the crown in mid-spring. If low temperatures hit -10 degrees F, it may kill an un-mulched plant; protect any zone 6 perennial with thick layer of mulch. General foliage decline may occur in hot and humid summer climates of the Southeast US but this is rarely a problem in Kansas or Oklahoma.
