Eryngium(Sea Holly)

Sea Holly provides unique interest in the garden with their spiny-toothed leaves and clusters of teasel-like blossoms. They also offer versatility as they do best in poor soil with little water and baked conditions. Sea Holly's 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. Remove spent flowers to prevent excess self-seeding. Deer resistant.
