Description

Let your summer sparkle with this gleaming highlight, Eryngium 'Magical Silver'! With frosty-looking cool green blooms, this sea holly will provide lasting interest through the season. Not only is it a great-looking and easy-going garden plant, but bees and butterflies will be keen on its nectar-rich flowers too. Strong, upright stems are self supporting and the display is prolific and enduring—as if that wasn’t enough, snip a few stems and you’ll find they’re amazing cutflowers too! 

Eryngium 'Magical Silver' remains strong and attractive for an impressive amount of time. The foliage is a soft sage grey-green, the blooms, from July to September, are similar hue but with a lustrous, icy glaze. When the colour fades in autumn, the plant stems and seedheads of Eryngium planum 'Magical Silver' remain a structural feature in a border. This fully hardy, drought tolerant perennial isn’t fussy, but does best in free-draining poor or sandy soils. If you have a gravel area or a sun-baked border, include this starry number and enjoy its undemanding charm.

With their powerful and bold appearance, eryngiums or sea hollies are known to symbolize independence and attraction.

Useful information

    • Soak your Eryngium 'Magical Silver' roots in water for 3-6 hours prior to planting.

    • Plant your "Sea holly" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
