About this plant
Artemisia 'Powis Castle' is an attractive perennial hybrid known for its finely dissected, silvery-gray foliage that adds a soft, textured element to gardens. Originating from the mix of species found in Europe and Asia, this plant was named after Powis Castle in Wales, where it was first cultivated. Its aromatic leaves provide a lovely contrast in mixed borders and perennial beds, enhancing the visual appeal of surrounding plants.
Blooming in late summer, 'Powis Castle' may produce small, inconspicuous yellow flowers. The foliage remains a focal point throughout the growing season, providing a sense of tranquility in both formal and informal garden designs. This hardy perennial is particularly valued in drought-tolerant landscapes, where its resilience and unique texture shine.

Design tip
Fall bloom is its strength, and it earns a place near a path or seating area used late in the year. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
