Easily recognised by their ruff of spiky bracts surrounding a prominent, cone-like centre of tiny flowers, sea hollies make a bold statement in a sunny border or gravel garden. This variety has deeply cut, deep blue bracts held on stiff, blue stems in July and August. The attractive, dark green, marbled foliage, which appears before the flowers, is shown off to best effect planted in gravel. Or try it in bold clumps among grasses. Eryngiums are also perfect for use in dried flower arrangements.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.
