    Branched teasel-like pale green flowers turning to steel-blue are surrounded by narrow silvery white bracts in summer. This rosette-forming perennial is great for the front or middle of a sunny well-drained border. The attractive foliage is displayed to best advantage if the plant is mulched with or planted in gravel. It is a short lived perennial which self-seeds freely.

  • Garden care: Lift and divide large colonies in spring. Avoid the temptation to cut back the flowerheads in autumn as they provide interest in the winter garden.
