Late season color is usually defined by black eyed susans, sedum, ornamental grass, colored foliage and fall annuals. But have you heard of a compact shrub with silvery foliage and blue flowers that comes into its prime in late August? Caryopteris x clandonensis, also known as blue mist shrub, happens to be that plant.
Blue mist shrub will fit any small space and can create a beautiful border, as it reaches a maximum height and width of three feet. This low-maintenance plant will bloom from late August to the end of September. Plant in average, well-drained soil with a lot of sun to achieve best results. Blue mist shrub is also a great addition to your butterfly garden. Use companion plants such as blanket flower, coneflower and shasta daisy to extend your butterfly season.
