Sea Holly - Blue Star, 1 Pack
Eryngium alpinum - Blue Star
A stunning alpine sea holly, Eryngium alpinum ‘Blue Star’ produces metallic steel-blue, spiky flower heads atop strong, upright stems. Blooming from midsummer into early fall, these globe-like blooms (4 cm wide) shine against silvery-green, deeply divided foliage. Reaching 70–90 cm (27–36″) tall with a 45–60 cm (18–24″) spread, it’s ideal for sunny borders, rock gardens, or dramatic cut/dried flower displays. Exceptionally low-maintenance and deer-, rabbit-, and drought-resistant, it thrives in full sun on dry, well-drained soils and is a favorite of bees and butterflies.
