Tripartite Sea Holly, Tripartite Eryngo
Eryngium x tripartitum (Tripartite Sea Holly) is an upright perennial with a basal rosette of coarsely toothed, gray-green leaves. From mid-summer to early fall, wiry, violet-blue branching stems bear cone-shaped, thistle-like, metallic-blue flower heads. Each flower head is surrounded by a ruff of slender, spiny, dark blue bracts. Attractive to bees and butterflies but deer resistant, this striking Sea Holly is good for cutting as well as the border.
