#ProPlantTips For Care

Truly doing its absolute best in full sun and sharply drained soils, Blue Glitter just shines in the spotlight, just like the punk-rocker it is!

Cut back each year before new growth begins for a full, branched plant. A durable specimen, Blue Glitter performs amazingly in a wide variety of climates but is truly accomplished in hot, sunny conditions.

Eryngium does not like to be over-watered. Preferring rich, fertile soils, but tolerant in more demanding, less than optimal settings, 'Blue Glitter' adapts to almost any setting that has well-drained soils. Even thriving in poor soils. Just be sure to water regularly when first planted, to ensure it gets established.

Blue Glitter will spread to form a small patch in a hot sunny area. You will find that the flower color tends to be more intense in higher temperatures.

Plant Blue Glitter Sea Holly in a sunny location and you will be glad you did! It will add unique color and texture to your garden, and provide your home with high-style floral bouquets!
