Yes you can, at least for a number of years. By containing it anyway it will not grow so near it's maximum size. You probably won't need to prune it either which would reduce it's flowering as the root restriction will reduce it's ultimate size. Use a compost with loam added such as Westland with John Innes or use a multi purpose with good top soil added. It's not critical but a mix, say 50/50 is ideal. In it's second year, give the occasional liquid feed. You may get up to five years in a largish tub but don't forget to water well and regularly as this shrub is very unforgiving being able to grow happily in quite saturated soils.

this is a very slow growing plant so the need to prune probably wont arise, more trim to shape after a few years.
Agree with fractal about the rest.

Thank you, Stevebuk. This is part of a retirement present and I want to ensure that I can look after it and enjoy the beauty of the flowers and the autumn coloured leaves.
