Artemisia 'Powis Castle'

Wormwood

• Position: full sun
• Soil: well-drained, fertile soil
• Rate of growth: fast-growing
• Flowering period: August
• Hardiness: fully hardy
  
  Artemisias are prized for their light, almost silver, aromatic foliage rather than for their flowers, which are dull and insignificant. This cultivar has fine, fern-like, aromatic leaves and tiny, yellow-tinged silver flowers in August. The billowing foliage of this woody stemmed perennial is ideal for a sunny rock garden or border. Although it's one of the hardiest varieties of wormwood, do plant it in a well-drained site, as the plant is likely to be short-lived in poorly drained soil.
  
  
• Garden care: Cut back stems back to ground-level in autumn and apply a generous mulch of well-rotted garden compost or manure around base of the plant.
