Blue Glitter Eryngium is a striking specialty cut flower that brings an otherworldly shimmer to fresh arrangements and dried displays. This open-pollinated cultivar of Eryngium planum produces compact plants hardy from zones 3 to 8, thriving in lean soil and low-water conditions that would challenge most ornamentals. From seed to harvestable flower takes a full year, but the payoff is unmistakable: metallic blue bracts that hold their color whether fresh or air-dried, making this a treasure for florists and home gardeners seeking long-lasting, low-maintenance blooms.

The flowers dry beautifully while retaining their luminous blue color, whether hung upside down or preserved in desiccant. Compact growth keeps this plant tidy in the garden, and its frost-hardy nature means it can overwinter in cold climates. The entire flower head and bracts turn brilliant blue when ready to cut, giving you a clear visual signal for harvest. Once dried, these blooms last for months without fading, earning their place in any dried flower enthusiast's garden.
Blue Glitter Eryngium is grown exclusively as a specialty cut flower for fresh arrangements and dried flower work. Cut when the entire flower head and bracts have turned blue, the stems hold their color beautifully in water for extended periods. For dried arrangements, the flowers can be hung upside down to air dry or dried in desiccant to preserve the color even more vividly. Florists prize these blooms for their unique metallic blue tone and remarkable longevity in both fresh and dried forms.

Sow seeds 10 to 16 weeks before your intended transplant date. Do not cover the seeds, as light is required for germination. Bottom water or mist lightly to avoid displacing the seeds with water from above. Keep the soil moist but not waterlogged during germination at 60 to 70 degrees Fahrenheit. Seedlings will emerge slowly; once they develop their first true leaves, transplant into cell packs or 2 to 4 inch containers and allow 5 to 8 weeks of growth before hardening off.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days, then transplant outside after the last frost date in your area. Space plants 18 inches apart in full sun. Plant into soil with a pH of 6.0 to 7.5, ensuring drainage is excellent to prevent root rot.
Cut flowers when the entire flower head and bracts have turned blue or white, depending on the specific cultivar. This color change is your signal that the bloom is ready and at peak quality. For fresh arrangements, cut in the early morning and place stems immediately in water. For drying, cut at the same stage and hang bundles upside down in a warm, dry, well-ventilated space, or use desiccant to dry more quickly while preserving maximum color.
