Add to wish list

A great plant to add contrasting foliage interest to the front or middle of a sunny border, Eryngium giganteum Big Blue has teasel-like cones of steely-blue flowers – like thimbles –  surrounded by a ruff of silvery blue spiny bracts. Held on stiff, branched stems, the deeply divided leaves are silver-green and spiky. An interesting accompaniment to grasses or other architectural plants.

Keep the flower heads on all winter, as they look striking.

This Alpine Sea Holly is a rosette-forming biennial, but self-seeds freely. It's a popular choice for flower arrangements, both fresh and dried.
