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 of Eryngium bourgatii Eryngium bourgatii Picos Amethyst, 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:
    Eryngium thrives in poor to moderately fertile, well-drained soil, ideally in full sun, while avoiding areas prone to wet winter conditions.

    To enhance winter interest in your garden, resist cutting back the striking flower heads in autumn; instead, leave them to add structure through the colder months.

    In spring, trim back the old stems to make way for fresh growth from the emerging foliage, ensuring the plant remains healthy and vigorous for the new season.
