Eryngium giganteum 'Silver Ghost'
giant sea holly
Teasel-like pale green flowers, which turn to steely-blue as they mature, are surrounded by a ruff of silvery white bracts. This rosette-forming biennial is great for the front or middle of a sunny, well-drained border. The attractive foliage is displayed to best advantage if the plant is mulched with or planted in gravel. This plant is a biennial, but self-seeds freely. It's also ideal for use in dried flower arrangements.
