Eryngium planum ‘Blaukappe’

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.

 

<i>Eryngium planum</i> ‘Blaukappe’

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' 0" – 2-1/4' high x 18" wide.

Hardy to zone 4.
