There is a nice one where I work in Seattle, planted near the entry I use, I has been there for many years. I I really like the flowers and the berries, so much that I bought seeds for the golden leaved cultivar, and swiped some seeds from the shrub I like too. In that location, it is a nice shrub about 5 feet tall, seems to stay about that size. I don't see suckers or volunteers nearby, in fact it seems to be a very mannerly shrub. Of course, Seattle is very different from Georgia. I just looked it up in the USDA Plants Database, it has become naturalized in California but no other states in the U.S. I would say it has had a sufficient chance to become invasive, and does not seem to be on any watch lists for Georgia, so if it was me I would give it a try.
