The pleasantly aromatic and lacy silvery gray foliage of Artemisia ‘Powis Castle’ can either mix well with pink, lavender or light blue flowers, or contrast against bright red or orange. The dark angular leaves of bronze New Zealand flax or bronze cannas are striking against its low and softly mounding form, which stays less than two feet tall and not much more than twice as wide. Contrary to how Artemisia ‘Powis Castle’ enhances the color of other flowers and foliage, its own flowers are not much to look at, if they get noticed at all.

Foliage is fluffiest if mature plants get pruned down at the end of winter. New plants can be propagated by division in spring or autumn. As plants get established, good drainage becomes more important than frequent watering.
