Im sorry to be in the minority on this thread. Love me some nandina! The laciness, pretty fall leaves and if course stunning red berries. But I'm a shade gardener. Nandina grow suuuuuper slowly for me. And I don't have a hedge full if them. Even in what little sun I do have, they are manageable. I know nandina are said to like full sun. Perhaps giving them everything it wants is not such a good idea?
