Eryngium zabelii 'Big Blue' – Sea holly with impressive steel-blue flowers

Eryngium zabelii 'Big Blue', better known as sea holly, is a spectacular perennial that immediately catches the eye with its large steel-blue flowers and striking silver-coloured foliage. This special cultivar is a real eye-catcher in sunny borders, prairie gardens, and modern garden designs. Thanks to its vigorous growth, long flowering period, and striking colour, 'Big Blue' forms a beautiful architectural element in any garden.

From summer onwards, the enormous steel-blue flower heads appear on sturdy purple-blue stems. The striking flowers are surrounded by spiny bracts that give the plant its characteristic appearance. The glossy silver-grey foliage forms a beautiful contrast with the intensely blue flowers and continues to offer decorative added value even outside the flowering period. The sturdy stems ensure that the plant remains upright, even in wind or rain.

Eryngium zabelii 'Big Blue' thrives in a sunny location in well-drained soil. Once established, this hardy perennial is highly resistant to heat and dry conditions, making it ideal for low-maintenance gardens. Furthermore, the nectar- and pollen-rich flowers attract plenty of bees, bumblebees, and butterflies, allowing this sea holly to make a valuable contribution to a biodiverse and insect-friendly garden design.

'Big Blue' is also particularly popular as a cut flower. The flowers retain their color and shape for a long time, both fresh and dried, and are widely used in bouquets and floral arrangements. Combine this striking perennial with ornamental grasses, Lavandula, Salvia, Perovskia, or Echinacea for an atmospheric border with a natural look. With its unique colors, robust character, and long-lasting ornamental value, Eryngium zabelii 'Big Blue' is a true asset to any sunny garden.
