Blue Glitter Sea Holly, Eryngium planum 'Blue Glitter', is a visually striking tough-as-nails perennial native to coastal regions of Europe and North America. The unique, spiky, intensely colored, silvery-blue leaves have distinctive thistle-like flowers that stand above the basal rosette of blue-green, deeply toothed leaves. As the name suggests, when sunlight hits Blue Glitter Sea Holly just right, they shimmer and glow an electric blue color rarely seen in the landscape.
Blue Glitter Sea Holly is tolerant of sandy and gravelly soils and salt spray, making them ideal for coastal and water-wise gardens. They grow in Hardiness Zones 5-8, reaching 3 ft tall with a spread of 1-2 ft. wide. This distinctive perennial delivers form, texture, and electric blue color in an easy-care package, and is equally striking used in floral arrangements.
Blue Glitter Sea Holly Care
Blue Glitter Sea Holly loves the sun, so plant it in a sunbaked area that gets at least 6-8 hours of direct sunlight per day. Avoid planting in rich soils, as Sea Holly prefers lean, sandy, or gravelly soils; all soils should be well draining as soggy soils can lead to root rot. Blue Glitter Sea Holly has a narrow hardiness growing range, so if extreme cold temperatures are expected, apply a few inches of organic mulch around the base of the plant to help protect the roots.
Blue Glitter Sea Holly doesn’t require a lot of maintenance. Deadheading the thistle-like flowers will encourage new blooms. Trim back any foliage that has been damaged to improve the overall appearance and health of the plant. Cut the spent foliage a few inches from the ground in early spring to make room for new fresh growth.
Blue Glitter Sea Holly Spacing
When planting Blue Glitter Sea Holly, space plants at least 18 inches or more from each other in order to allow plenty of sunlight and air circulation between each plant.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
