Eryngium

Sea Holly

Dynamic is a rare adjective to apply to a plant, but it’s the best we can think of to describe Eryngium. From its leathery lobed leaves to the spiny, decorative bracts that host the flower, the 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 well drained soil in the open sun, and are an arresting addition to the mixed border, especially when planted amidst Rudbeckia, the Achilleas, and grasses.

Eryngium ‘Big Blue’ 

This hardy Eryngium is big on blue—the electrifying, iridescent kind that promises to tantalize any garden visitor. A Blooms of Bressingham introduction, ‘Big Blue’s green spiky 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 silvery white bracts and green cones, over the course of several weeks, gradually transmute amazing cerulean shades, imbuing even the stalks below.
