With clusters of striking maroon-red flowers, Eryngium 'Magical Red Thunder' creates a dramatic visual display for gravel and coastal planting schemes as well as traditional sunny borders. Its rounded, berry-like blooms are encircled by delicate pale bracts, giving the plant an intricate, textured appearance. This hardy, Mediterranean cultivar features tall, robust stems that can reach up to 2m (6ft), making it an impressive architectural addition to garden borders. The toothed, clump-forming basal foliage provides a sturdy foundation for the towering flower spikes. Ideal for adding height and texture, this herbaceous perennial thrives in sunny, well-drained sites, and is perfect for attracting pollinators.

How to care for Eryngium Magical Red Thunder (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.
