Eryngium planum 'Blue Glitter'

Eryngium makes an excellent long lasting cut flower.

Common Name: Sea Holly

Looking for a perennial that will grow in that hot, sun-baked spot in your landscape? Sea Holly is just the plant! It thrives in that type of climate, and even grows in high-salt soils too (think seaside).

Sea Holly is adored by florists and gardeners alike for its unique and long lasting, blue, spiny flowers which add interesting color and texture to bouquets or the garden. They are produced on intensely silver-blue stems and stand high above the basal rosette of blue-green, deeply toothed, smooth textured leaves.

'Blue Glitter' is an improvement over older varieties because it matures quickly, produces a greater number of flowers, and has a more intense blue flower color. It does not require vernalization to bloom, which is an advantage to gardeners in southern zones.

This species of Eryngium is one of the hardiest and it has proven to be a reliable, long-lived perennial.
