Also known as ‘Sea Holly’. Eryngiums grow well in coastal locations and they also look wonderful in gravel gardens and herbaceous borders.
A striking, ornamental, bee-friendly plant with colours ranging from grey to intense blue, the thistle-like flowers are made up of tiny flowers packed together in a tight cluster. In winter the seed heads add interest to your garden and the flowerheads are great for cutting and using in dried flower arrangements.
Eryngiums need plenty of sunshine and free draining soil – planted at the foot of a wall is a good position as the soil will remain dry over the winter. The flowers of the Eryngium are also good for honeybees and hover flies, so if you’re looking for something eye-catching with dramatic colour, and good for insects, then this is the plant for you!
