Seaholly

Spiny, silvered, and sea-swept, Eryngium maritimum is a coastal classic with architectural poise and true wild beauty. Native to Europe’s shorelines, this striking perennial flourishes in sandy, free-draining soils and basks in full sun. Its metallic-blue blooms and jagged foliage bring bold texture to gravel gardens, wild borders, and drought-tolerant designs—while offering a rich nectar source for bees and butterflies.

Naturally resilient and fuss-free once established, Blue Sea Holly thrives in poor soils, tolerates salt-laden winds, and shrugs off drought with ease. Sow with patience—germination is slow and benefits from cold stratification—but once rooted, it’s here to stay.
