The word "serendipity" means an unexpected occurrence, and what a fitting name for this sport of the popular 'Millenium'! The sport shares all of the qualities that made 'Millenium' great, but with attractive blue foliage. Globe-like, rosy-purple flowers match the parent and are produced profusely in mid to late summer. When crushed, the leaves will emit a smell of onion.

Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.
