An easily grown 'Sea Holly'. The clumps of leathery deep green heart-shaped leaves support the most metallic blue of all Sea Holly flowers with spiky, blue grey bracts. The profusion of flowers gives the impression of a blue haze when planted amongst other perennials. Performs well in well drained soil and full sun. Handles neglect and drought but not Winter wet or poorly drained soil. Height to 1 metre in flower.
