Eryngium Blue Glitter is a fast growing eryngium that can add height to the back of a border and has a good stem length for fresh and dried cut flower production. 'Blue Glitter' has silver blue stems that unfold into an abundance of small shimmering blue pincushion flowers. Best in hot sunny conditions with a rich fertile soil that needs to be well drained. Actually a perennial but only for very mild areas that are frost free in winter.
