Anita. One thing I'm wondering about is whether these were only planted last year because one was pink and one was blue. That suggested to me that they were newly purchased otherwise the colours would have been closer as they adapted to the soil pH. It sounds like they were not pruned last year since Anita's brother said leave them alone. In that case I wonder if they are growing in a zone too cold for them as Elaine suggested. It would help if we knew where they were growing and what their names are. The blue and pink ones are typically not as hardy as others.
