Eryngium 'Sapphire Blue' - Sea Holly. My garden tips: thrives in low fertility soil and dry, sunny conditions. For best flowering and blue color, give all day sun and no fertilizer! Great with ornamental grasses, particularly the blondes!
Eryngium plants, also known as sea holly flowers, make striking additions to the garden. Mostly native to Europe and the Mediterranean, these plants generally grow anywhere from 18 to 36 inches tall with a one-foot spread. Their green or silvery-blue stems give way to green or blue cones surrounded by spiky silver, white, green, blue or violet bracts, which bloom from summer throughout fall.
The silver-blue petals and thistlelike foliage of sea holly (shown here with bright green dill) stand almost hip-high in the flowerbed. This ghostly giant is a biennial, and the plant readily reseeds itself. Grows comfortably in Zones 5-8.
