Very healthy very large upon arrival

After a delay in receiving these I’m extremely happy with the size and health of these. Growing nicely… gave sprouted stems and I’m waiting for the color change. Very resilient in the direct sun.

Blooming when We recd it Oct 1Still blooming Oct 22. Hoping it spreads in the Spring. PlusThe deer don’t eat it!!

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.

If you ever want personalized care tips or have more questions as your garden grows, please don’t hesitate to reach out. We’re here to support you every step of the way!

Rooting for your garden’s success,
Your Nature Hills Plant Care Team

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,

I had this plant once and wish I could find another. When I planted it, it was green, nothing really to brag about. One day I walked past it and to my surprise, it was a beautiful blue from ground to tip. I loved it.
