    An upright, herbaceous perennial with spiky, highly divided, silvery-green foliage from which flowering cones emerge encircled by a ruff of long and prickly, intense-blue bracts. ‘Big Blue’ lives up to its name and would make a bold addition to dry, sunny borders and gravel gardens where the ‘everlasting’ blooms will attract masses of bees.

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