    From the clumps of feathery foliage, wooly white stems arise in summer bearing pale to purple-pink spikey flowerheads, which help draw in the bees and butterflies. It's a great addition to a cottage garden or wildlife-friendly border.

  • Garden care: Deadhead regularly to prolong flowering. In autumn cut the faded flowerheads down to the ground and compost the dead stems.
