About the product

Thistle-like leaves and steel blue stems and flowers makes the alpine seaholly a favorite perennial for gravelly gardens.
Eryngium alpinum is a hardy herbaceous perennial native to dry rocky mountain slopes of southeastern Europe, including the Alps. Decorative perennial for cutting and drying.
In summer it produces plume-like flowers with a barreled cluster of fertile, tiny white or blue flowers surrounded by multiple rows of spiny bracts (modified leaves) of silvery blue to blue-purple. The long-lasting flowers are borne atop steel blue, branched stems and are highly attractive to bees and butterflies. If the seedheads are allowed to mature, it may self-sow.
