Eryngium zabelii 'Big Blue' – Sea Holly
On a sunny summer day, 'Big Blue' is nothing short of electric. Vibrant, intense blue cones rise above spiky green foliage, surrounded by breathtaking silver bracts that catch the light and stop garden visitors in their tracks. This is a plant that earns its name — bold, architectural, and unforgettable. Thriving in sandy, chalky, or clay soils and loving the heat and drought that challenge lesser plants, 'Big Blue' is as tough as it is beautiful. An excellent cut flower, a magnet for bees and butterflies, and completely ignored by deer and rabbits. A must-have for the low-water perennial border.
