  • Artemisia ‘Powis Castle’ commonly known as Wormwood, is a go-to plant for adding soft texture and cool toned color to the garden. Its finely divided, silvery gray foliage has a soft, almost feathery look that contrasts beautifully with greener plants and adds a light, airy feel to planting designs. It forms a naturally rounded, mounding shape that works well in both structured and more relaxed landscapes.
  • While it is occasionally referred to as a flowering plant, it is really grown for its foliage. Any blooms are small and fairly subtle, so the real value here is the consistent color and texture it brings throughout the year.
  • This plant thrives in full sun and prefers well drained soil. It is highly drought tolerant once established and is a great choice for Mediterranean, coastal, and low water gardens. In fact, it tends to perform best with minimal summer water and good drainage, making it a reliable option for tougher planting areas.
  • Artemisia ‘Powis Castle’ typically grows 2 to 3 feet tall and 3 to 6 feet wide, creating a broad, flowing form that can soften edges, spill slightly over borders, or fill in space between larger shrubs. It responds well to occasional pruning, which can help maintain a fuller shape and prevent it from becoming too woody over time.
  • It is well suited for USDA zones 7 through 10 and performs especially well in climates with dry summers.
  • Artemisia is generally considered non toxic, though its aromatic foliage is not typically eaten by pets or wildlife.
  • With its soft silver color, low water needs, and easy going nature, ‘Powis Castle’ is a reliable staple that pairs well with just about anything in the garden.
