Eryngium – Sea Holly
Eryngium planum, commonly called sea holly, is a remarkable clump-forming perennial that features a summer bloom of steel-blue, thistle-like flower heads on branched stems rising from a rosette of dark green basal leaves. Attracts pollinators! Stiff, branched, violet-blue stems (to 32” tall), bearing abundant, egg-shaped, thistle-like, violet-blue flower heads, rise from each basal rosette in summer. Each flower head is a spherical-cylindrical umbel that is packed with tiny, stemless, violet-blue flowers. Summer bloom is often profuse.
Excellent for cut or dried flower arrangements.
