A superb evergreen shrub prized for its elegant, silvery-grey foliage that adds year-round interest and texture to the garden. Its finely divided, aromatic leaves form a beautiful, mounding habit that works perfectly as a structural plant in borders, gravel gardens, or as low hedging. Exceptionally drought-tolerant and low-maintenance, it thrives in full sun and poor, well-drained soils, making it ideal for challenging, dry spots. The foliage provides a stunning contrast when paired with vibrant flowering plants or dark-leaved shrubs. Hardy and deer-resistant, it's a trouble-free choice for adding sophisticated silver tones to both formal and informal garden designs.
