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
wooded enough to be a perennial. 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.
