There are many species of this plant found all over the world, and the Southeastern United States has this beautiful variety. I have to admit I'd never heard of it until I saw it growing in a community garden in Philadelphia, Pennsylvania, USA. They can grow to around five feet high and five feet in girth, and after blooming they are just covered with these gorgeous berries.
The berries are highly astringent and don't taste terrific, but they serve as a survival food for birds (Bobwhite Quail, for example), some animals (Whitetail deer, etc.), and even some caterpillars. People do make jams and jellies from them, but I can't attest to how good or bad they may taste.
