Eryngium bourgatii, otherwise known as Mediterranean Sea Holly is a striking perennial known for its spiky blue flowers and unique foliage. It forms low clumps of deeply lobbed dark green leaves marbled with white veins. Vibrant blue flowers appear on 60cm stems throughout summer.

Eryngiums love poor soils in hot dry conditions. Plant in full sun for maximum flower colour. Protect from frost. Cut back to the ground in late winter to encourage fresh new growth in spring and abundant flowering in early summer. Drought tolerant. Avoid transplanting. Tolerant of the toughest conditions, including coastal sites and poor soils. Good drainage is essential, especially in winter. Stake if necessary in fertile soils, and plant in multiples or among other perennials for support.
