ERYNGIUM 'BLUE SEA HOLLY'
This beautiful European sea holly forms clumps of heart-shaped leaves, over which a profusion of anodised, blue thimbles appear on vibrant stems. Tolerant of the toughest conditions, `Blue Sea Holly' may require staking in rich soils. This spiky character adds interest to our border and looks wonderful planted amongst agastache and coneflowers. Also a superb cut flower, much beloved by florists.

Eryngium planum & Echinacea
Sea Holly (Eryngium) is a great carrot relative with metallic violet-blue flowers that pollinators love. Coneflowers (Echinacea) not only pair well with them, but draw more pollinators and seed-seeking goldfinches in the fall. Longwood Gardens, PA
