Add item to quote to see pricing

Eryngium maritimum is an enchanting perennial, widely recognized as the Sea Holly. Hailing from coastal and dune locales, this sturdy plant captivates with its one-of-a-kind metallic blue hue. Topping out at a compact 2 feet tall, the Sea Holly unfurls pointed, silver-tinted leaves while its exotic flowers - an almost alien pairing of cone-shaped heads and piercing bracts - astound in a striking silver-blue. Prepare for a prolific display from late summer to early fall as it stands firm against pests, drought, and ocean sprays, needing little more than a sunny, well-drained spot to flourish. Meanwhile, the Sea Holly's compelling allure doesn't end with aesthetics: a certified favorite with both butterflies and bees, this low-maintenance addition to your garden serves a practical purpose alongside its bold visuals. Whether you're curating a coastal-inspired vista or enhancing an inland habitat, the Sea Holly assures an impactful contribution to every botanical collection.
