Cultural Significance
Globe Thistle's name comes from Ancient Greek "echinos" (hedgehog) and "ops" (appearance), referring to its spiny, spherical flower heads. In the language of flowers, thistles traditionally symbolize nobility, protection, and resilience. The plant's ability to thrive in poor, dry soils makes it a symbol of self-reliance and strength. Globe Thistle has been valued in European gardens since ancient times and remains a classic cottage garden favorite. Its architectural form and steel-blue color provide striking contrast in modern perennial borders, representing the blend of wild beauty and cultivated grace.Shop Our Floral Collection
