Eryngium, commonly known as Sea Holly, is one of the most architecturally dramatic and visually distinctive plants in the garden — spiky, thistle-like flower heads in vivid shades of steel blue, violet, and silver-blue, surrounded by sharp, star-shaped bracts that give the plant an almost metallic, otherworldly appearance. Native to coastal habitats, meadows, and rocky terrain across Europe, Asia, and the Americas, eryngium has over 250 species and has become a prized element in contemporary floral design and naturalistic garden planting for its bold texture, long bloom time, and extraordinary color. Unlike most blue flowers, eryngium holds its color exceptionally well when dried, making it a favorite for both fresh and dried arrangements. Our Eryngium collection captures that bold, sculptural beauty in original, USA-made artwork printed on durable, commercial-grade products built for everyday use.
Browse our full Eryngium collection and find the perfect piece — from eye-catching garden flags that bring that steel-blue drama outdoors to cozy pillows that carry the striking beauty of sea holly inside.
