Eryngium
Sea Holly
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.

This hardy Eryngium is all about blue—the electrifying, iridescent kind that promises to tantalize any garden visitor. A Blooms of Bressingham introduction, ‘Big Blue’s spine-edged green foliage and thick stems create an intriguing candelabra-shaped base for the bright 4 in. wide inflorescences. A blue drama is yours for the viewing as frosty-white bracts and green cones, over the course of several weeks, gradually transmute stunning cerulean shades, imbuing even the stalks below. (PPAF)
