My grandparents had a tradition of growing a Josephine Bruce rose in the garden of each house they moved to. My granddad died before I was born but my grandma has kept up the tradition, until now. She's recently moved into a flat with a small balcony and I'd love to buy her one of these rose bushes for her as a housewarming present. I have no idea about roses and I can't find much information online. Would it be suitable to keep in a container?
