Caryopteris incana ~ Blue Beard
Caryopteris incana can be used in many of the same situations that you would use a lavender. I like to slip some in when too much lavender has been used already and a different plant would catch the eye. Caryopteris incana is almost soft, yet woody enough at the base to be a shrub. When the temperatures dipped into the teens it died back. The dark blue flowers of Caryopteris incana will stand out in any late summer garden.
