'Reading Show' has such a rich deep blue corolla. When the entire bush is in full bloom, it is such a treat to see. I think a white blossomed annual ground cover would be a nice companion plant for this one. 'Reading Show' is one of my older bushes and like 'Quasar' has survived many a hot summer out in the full sun and the occassional freeze every winter. It did sustain some damage this last December. But not as much as the Walz Bella next to it. Sometimes that happens. One plant will be fine and the one next to it will be damaged. It is already putting out new growth though, so I am not worried. A bit of a trim and it will be blooming again in no time. It is going to be a star in my floral arrangements this spring!
