Easy to grow and ideal for naturalised planting schemes this delightful knapweed will act as a magnet to nearby wildlife. The flowers appear for a really long period from early summer and if you leave them on the plant once they have faded they will form beautiful seedheads. These will open like silver stars to release their seeds (a treat for the birds) and then go on to add structural interest to the winter garden.

  • Garden care: Stake with bamboo canes or brushwood before the flowers appear. Deadhead regularly to prolong flowering. In autumn resist the temptation to remove the faded flowerheads as the subsequent seedheads are really attractive in winter. Lift and divide large clumps every three years in spring.
