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.

  • Typically growing in a shrubby mound to 2-3′ tall (60-90 cm) and as wide, this foliage plant may spread to 3-6′ (90-180 cm) if not trimmed.
  • Evergreen in warm winter climates.
  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society (1993)
  • Thrives in poor to moderately fertile, dry to medium moisture, well-drained soils in full sun. Excellent soil drainage is essential. Good selection in poor, dry soils.
  • Focal point as a single specimen. It fits beautifully in any bed of perennial flowers and is a lovely addition to the herb garden.
  • Drought, deer, and rabbit tolerant!
  • Prune plants before new growth starts in the spring and leave 12-18 inches (30-45 cm). Never prune stems to the ground. Foliage may also be lightly sheared in summer to shape.
