I have a very narrow strip of earth, about 10 inches wide, alongside a fence which is north facing and always in total shade. I have some winter and summer heathers which seem quite happy there and a tiarella, which also does ok. But I would like some brighter summer colour along this fence. I would like low growing stuff as it also borders a path. I am quite fond of fuchsia, and wondered about the hardy dwarf shrubs. Any advice and any ideas please would be welcome.
