Answer: Your neighbor might wish to consider a Bluebeard or Blue-mist shrub (Caryopteris x clandonensis). Also sometimes called Blue-spirea, this small shrub should do well in a sunny spot with a well-drained loose soil. It blooms during the summer on new wood and is quite lovely. The variety "Longwood Blue" grows to approximately four feet high and wide. In some winters this shrub acts like a herbaceous perennial and dies back to the ground but will regrow during the course of the summer and bloom normally.
