Artemisia 'Powis Castle' is a hardy, evergreen perennial shrub prized for its finely divided, silvery-gray foliage and soft, feathery texture. A hybrid variety believed to be a cross between Artemisia arborescens and Artemisia absinthium, it grows in a rounded, bushy form reaching about 2 to 3 feet tall and wide. The aromatic leaves release a pleasant, herbal scent when touched, making it a popular choice for sensory gardens and borders. While it produces small, yellowish flowers in late summer, the plant is typically grown for its striking foliage rather than its blooms.
Exceptionally drought-tolerant and low-maintenance, Powis Castle thrives in full sun and well-drained soil, making it ideal for xeriscaping, Mediterranean-style gardens, and rock gardens. It resists deer and pests, and its strong architectural form makes it a great companion to more colorful flowering plants. Regular pruning helps maintain its shape and encourages dense, healthy growth. Its silvery foliage also contrasts beautifully with green, purple, or dark-leaved plants, adding light and visual interest to mixed plantings throughout the growing season.
