A compact, mounding, deciduous shrub, valued for its late summer to autumn bloom time. Aromatic, silver backed foliage provides the perfect foil for the deep blue flowers, said to be the bluest of all Caryopteris. Growing 2 ft. tall by 2 ft. wide in full sun where it will be drought tolerant once established. An excellent addition to the habitat garden where bluebeard offers copious nectar for a variety of late season native bees and honeybees. Butterflies and hummingbirds work the flowers too. Deer resistant.
