The soil type you describe is what is usually recommended. I have a lot of clay in my soil so I planted my bushes on a slope that is too steep to mow. That seems to provide enough drainage. They did have a brief fungal infection on their second year, I treated with sulfur powder and haven't had any problems in subsequent years. A cheap pH meter says my soil is around 5, but I don't put a lot of confidence in its measurements.
The flowers are also beautiful and have a pleasant aroma.
Keep it in your peripheral but don't stare directly.
