Features of Wormwood


Dramatic mound shaped plant grown for its very fine textured silver to almost white foliage. Flowers are insignificant. Grown for its foliage. May have hardiness issues so placing the plant where it gets some winter protection is helpful and making sure it has very good drainage during the winter.


  • Needs very well-drained soil in full sun location.
  • Cutting back occasionally helps to maintain form and size.
