Hidcote is a perfect choice for low hedges, edging or creating borders. Excellent for crafts and dried flowers as they retain their color. Blooms once in late spring or early summer. May have a second and third flush of flowers during the season if the flowers are cut soon enough.

Eryngium bourgatii 'Picos Blue' (Mediterranean Sea Holly) is a lovely addition to the garden or mixed containers for various reasons. Unlike other species, its deeply lobed, dark green foliage, which appears before the flowers, is elegantly marbled with broad silvery-white veins, making it very attractive and luminous.
