Mystery Shrub ID.

11-20-13 SHORT HILLS: Thanks and kudos go to Alison, horticulturalist extraordinaire, for her ID of the mystery shrub. She named it as blue mist or bluebeard, both are correct as common names for, ta da, Caryopteris x clandonensis 'Longwood Blue'. The shrub is hardy to Zone 5, drought tolerant, has silver-green leaves and blue flower cluster in late summer, is aromatic and attracts pollinators, including butterflies.
