Caryopteris x clandonesnsis 'Dark Knight'
I found a great plant for the portion of my yard that's being re-worked. The hummingbirds and bees love it, too.
Things are a little shabby in this corner of the yard, but the Dark Knight Bluebeard will be a nice mass next Summer to compliment in texture and color the Dusty Miller and Rhododendron.
Here are some pics of what I am looking forward to next summer and the summers after that.
