Commonly known as Sea Holly, Eryngium ‘Blue Steel’ produces stunning spires of small blue flowers surrounded by a spiky bright blue collar. Adored by pollinators, this perennial flowers from July to September and copes perfectly well in dry, hot and coastal conditions. Ideal for adding some texture to your sunny garden borders or as a beautiful addition to your wildlife garden. This eryngium also makes an exquisite cut flower either fresh or dried.

Grow sea holly plants on light, well drained soil in full sun. Eryngium plants particularly dislike cold, wet soil in winter which may cause the crown to rot. If planting on heavy soils, dig in plenty of coarse grit to improve drainage prior to planting.
