I would be obliged if someone could provide the name for this pink flowering tree. I had it cut back last year asit was getting out of control in the area it is situated by back gate. Is it Verbanum variety?

Super sunny warm day, the container plants had a water plus about six newly planted ones. The rest of the garden has to wait until it rains, I am not able to water things on slopes, and using a hosepipe would be asking for trouble with so many steps involved.
