Sea Holly 'Big Blue' (Eryngium x zabelii) is extraordinarily eye-catching with its multitude of intense, iridescent steel-blue flowers, 4 in. wide (10 cm), tightly packed into egg-shaped heads, that light up the garden throughout summer. Its beautiful texture and unique color that extends onto the stems and leaves, coupled with its long-lasting flowering, easy care and remarkable qualities as cut flowers make it a favorite of gardeners. A favorite of bees and butterflies too!
