Achillea 'Alabaster'

yarrow

• Position: full sun
• Soil: well-drained, including dry
• Rate of Growth: average
• Flowering period: August to October
• Hardiness: fully hardy
  
  Flowering later than many other yarrows, this one has the same attractive grey-green foliage, from which upright stems emerge bearing flattened heads of pale yellow flowers, which turn to milky white as they mature. After they have faded, the developing seedheads create an attractive silhouette, which remains interesting well into winter if you don't cut it back. A good mixer with other late perennials such as Asters, it also works really well with ornamental grasses.
  
  
• Garden care: Stake using bamboo canes or brushwood before the flowers appear. Cut down to the ground in late winter, but resist the urge to do this earlier, as the seed heads look lovely in the winter light. Lift and divide large clumps in late autumn or early spring.
