Hi Doreen,

What you most likely have is called powdery mildew.  It is very common to
certain types of plants:  zinnias, monarda, lilac are particular favorites.
There really isn't much you can do other than chose resistant varieties.
The problem is mainly cosmetic.  Spraying with a fungicide is a
possibility, but that only adds more chemicals to the environment and is
only a stopgap measure from what I understand.
