Eryngium is a family of thistle-like plants, also known as Sea Holly, that is highly regarded for its sculptural, spikey appearance and superb metallic colour.
The new variety, Eryngium planum Magical Blue Lagoon, is a particularly fine example. From afar the perennial appears to float in a miasma of purple and blue; close to, and as the heads mature, the blue is more defined and intense.
Eye-catching in form, the 'thistles' branch out from rigid stems and form multiple flower heads. The leaves are softer in shape and a lighter green than other varieties. Each head, bullet-shaped like a miniature teasel, is surrounded by a blue veined, spiny ruff creating a lacy outline that would be the envy of the Grimm brothers.
Position this fairytale plant in a hot, sunny border and watch as native pollinators happily navigate their way in.
