I am planning the planting for a baby memorial garden in a Cemetery in Yorkshire. I need to find suitable plants for a 10 metres long south facing border (backed by a stone wall) and a 8 metre long west facing border (backed by a fence). The garden is fully enclosed so its not exposed to the yorkshire elements. I'm not sure about the soil, I know in the area its can be quite heavy clay but it may be improved from the addition of mulch every year.
I want plants that will definitely survive, and are easy to maintain. I'm thinking about growing some clematis on trellis on the stone wall, and in the borders I would like mainly perennials with some shrubs that will look good in Autumn/winter when the perennials have all died back. I don't want anything that's too fast growing. I prefer shrubs that are no more than 4 ft in height. I like dogwoods for their winter colour but I think these might get too big??
Any help and ideas gratefully received
Thanks very much
