#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!

Start your garden off on a powerful note this year with spotlight-worthy Blue Glitter Sea Holly! Order today from Nature Hills Nursery, and get started on filling your landscape with unique, rock-n-roll style blooms!

Hi Paul,

Thank you so much for sharing your wonderful experience with the Blue Glitter Sea Holly! We're delighted to hear that it was blooming upon arrival and continues to flourish well into October—that’s a great sign it’s settled in nicely. It’s fantastic that the deer are leaving it alone too; they often steer clear of sea holly, making it a reliable and charming addition to your garden. As spring approaches, you’ll want to ensure the soil is well-drained but moist to encourage healthy spreading. If you'd like, we can provide some tips on companion plants or ways to optimize its growth—just let us know!

Wishing you happy planting,
The Nature Hills Plant Experts

Hi Paul,

Thank you so much for sharing your wonderful experience with the blue glitter sea holly! We're thrilled to hear that it's still blooming well after arriving on October 1st and that it’s showing such hardiness—including being deer-resistant, which is fantastic news for many gardeners. To help encourage spreading in the spring, you might consider providing well-draining soil and ensuring plenty of sunlight, as sea holly tends to thrive in those conditions. We also recommend lightly fertilizing in early spring to support robust growth.
