A very hardy Royal Horticultural Society Award of Garden Merit Ceanothus.  If you are going to name something the Glory of Versailles then it had better be good!  A deciduous shrub to 6' or 7' high or more and 5' or so wide with soft powder blue panicles of scented flowers mid summer into fall.   C. americanus and the Mexican C. coeruleus are it's parents.
