  This stunning yarrow will help liven up a sunny border or gravel garden with its large, flattened clusters of canary-yellow flowers. More resistant to flopping over than most other achilleas, it rarely needs staking and is long-flowering as well as drought-tolerant. The bright colouring of 'Moonshine' makes it a perfect partner for ornamental grasses - and the flowers look great when cut and added to a vase.
  
  
• Garden care: 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. Pull out seedlings as they appear, as they rarely match the host plant. Lift and divide large clumps in late autumn or early spring.
