How to care for Eryngium × olivierianum Big Blue ('Myersblue') (PBR):
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.
