With its striking silvery-white, thimble-shaped flowers nestled within spiky bracts, this standout perennial transforms any garden with its dramatic presence. Eryngium ‘Magical White Lagoon’ is a clump-forming plant that flourishes in well-drained soil and withstands drought once established, making it perfect for borders, rock gardens, or as a focal point in a dry-themed or Mediterranean garden. The highly divided, silvery-green foliage adds an architectural touch and provides a stunning contrast to its summer bloom, which also attracts bees and butterflies. Additionally, its resilience to rabbits and its suitability for both fresh and dried floral arrangements highlight its versatile charm.


  • 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.
