Evergreen thistle-like leaves and steel blue flowers makes the flat seaholly or blue eryngo a favorite perennial for sunny, gravelly gardens. Eryngium planum is a hardy herbaceous perennial native to dry rocky mountain slopes of southeastern Europe to central Asia. It has a dense basal rosette of heart-shaped, coarse, spiny dark green leaves that are leathery. In summer it produces plume-like flowers with a barreled cluster of fertile, tiny pale blue flowers surrounded by many spiny bracts (modified leaves) of blue-gray. The long-lasting flowers are borne atop branched stems that have blue-green lobed leaves. Flowers are highly attractive to bees and butterflies. If the seedheads are allowed to mature, it may self-sow.
It is a lovely and interesting perennial for sunny borders, and its cool, architectural flowers compliment many other brightly colored ornamentals. The flowers make long-lasting cutflowers for fresh and dried arrangements. (Info source:
