Teasel-like pale green flowers, which turn to steely-blue as they mature, are surrounded by a ruff of silvery white bracts. This rosette-forming biennial self-deeds freely and 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. Eryngium giganteum 'Silver Ghost' is also ideal for use in dried flower arrangements.
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.
