Amethyst Sea Holly, Amethyst Eryngo, Italian Eryngo
Extremely hardy, Eryngium amethystinum (Amethyst Sea Holly) is a compact perennial with a basal rosette of deeply cut, gray-green leaves, adorned with silver speckles and white veining. From mid to late summer, sturdy branching stems, tinged blue, bear small, thistle-like, blue-to-amethyst flower heads. Each flower head is surrounded by up-curving, silvery bracts. Attractive to bees and butterflies but deer resistant, this is a versatile plant, fitting well into the sunny border. Easier to grow than most, use it at the edge of a border, as a vertical accent or as a focal point.
