Eryngium planum Blaukappe

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.

With silvered, narrow spiky ruffs that cradle metallic blue round flower heads, ‘Blaukappe’ makes a sterling addition to dried or fresh bouquets. The vividly colored “blue caps” crest stiff-branched, sturdy bluish stems arising from a handsome green basal rosette of coarsely toothed, rounded and leathery foliage. Let its fantastic mercury-hued accents temper the bronzed blades of Stipa arundinacea.

Blooms June–September.

Size: 2'–2-1/4' high x 18" wide; hardy to zone 4.

Current Staff’s Favorite Plant

staff favorite plant

Our favorite plant this week: We love Geranium 'Bevan's Variety' for it's deer tolerant and stalwart habit, which sports richly colored, long blooming summer flowers. Named for the thick fleshy rhizomes by which it spreads, ‘Bevan’s Variety’ is one of the best ground cover plants for shady areas. Flourishing year after year in our older border with early flowering Brunnera and Euphorbia ‘Great Dixter’. Bearing clusters of intensely colored dark magenta flowers and decorative deep red sepals above soft green aromatic foliage.
