I Want To Find My Own Secret Garden

I love the idea of a secret garden, my garden isn't a secret but it's sort of mine. No-one else is interested. I have grown tomatoes, sweet peas, geraniums. Plus there are mombresia in the pond and bull rushes. I have tended the honeysuckle and a new crop of flowers are coming out. They are a gorgeous magenta colour. Not the yellow that grows by the roadside. In a few weeks when the tomatoes are finished I want to plant roses in the tubs. I also have a clematis but either the garden is not good for clematis or I am not good for clematis. There is no soil in my garden. The farm is on a steep hillside. If you dig down one cm it is solid rock.
