From its leathery lobed leaves to the spiny decorative bracts that host the flower, the dynamic Sea Holly has a sense of movement that is up and out. Excellent in fresh or dried arrangements, the flowers are borne on tall branching stems, and the terminal blooms hold their color while lateral flowers develop, until the entire stem is covered with mature blossoms. Eryngiums love sharp-draining soil in the open sun, and are an arresting addition to the mixed border, especially when planted amidst Rudbeckia, Achillea and grasses.
A snowy white multitude of plump conical flower heads perch atop pointed, widely spaced silver bracts. Leafy multibranching stems, pearly hued and steadfast, bolster the luminous blooms, while arising from an attractive dark green basal rosette defined by serrated leatherlike leaves and red-tinted petioles. Pair ‘Silver Salentino’ with Eryngium ‘Blue Glitter’ for a classic look.
