Artemisia Powis Castle

Good-looking, drought tolerant and fragrant, award-winner Artemisia ‘Powis Castle’ is a bushy sub-shrub, which is highly valued for its fernlike, silvery-white foliage, that easily blends with any flower bulbs and other perennial plants. Yellow flowers appear in late summer or early fall, but they are not spectacular and are best cut off to keep the foliage at its best.
