Eryngium alpinum
Sea holly Blue Star is a true star among perennials thanks to its unmistakable metallic sheen. The original species, alpine sea holly, comes from the southern Alpine regions and the Balkans, where it grows in sunny meadows and rocky slopes. It brings a uniquely distinct structure to flower beds, which stands out especially in naturally styled steppe and gravel beds. The Blue Star cultivar boasts striking, finely divided bracts in indigo blue to silvery colors, forming an impressive collar around the cylindrical inflorescence. This perennial is literally a magnet for bees, bumblebees, and butterflies, who appreciate its nectar. For its sturdiness and durability, sea holly is also highly valued in floristry. The flowers look great in fresh summer bouquets, but they put on an even bigger show in dried arrangements, where they retain their shape and color for a long time. If you leave them in the flower bed over the winter, they will provide an interesting effect even under a cap of snow or frost. It is an undemanding plant suitable even for beginners; it just needs well-drained, even poorer soil and plenty of sun.
