Powis Castle artemisia is a low mounding shrub, herbaceous in character, that grows 2-3 ft. tall, 4-6 ft. across. Silvery gray-green foliage is finely divided and soft in appearance; flowers are inconspicuous.
Discovered in Powis Castle, Wales, Powis Castle artemisia has quickly become a popular garden plant in the Inland Empire due to its relatively small size, soft texture and silvery-gray color. It grows well in full sun to partial shade, on well-drained soils with moderate to low amounts of supplemental water. It is best to treat this selection like an herbaceous perennial; it is often short-lived to 3-5 years and looks best when trimmed each year to maintain a compact shape. It combines well in mixed border plantings, spilling over walls and on banks in both Mediterranean and cottage garden plantings.
