Check to see if the soil is acidic, alkaline or neutral, before you go shopping for plants as some are very fussy about the conditions they like. As its in sun there is a huge choice of perennials which will like this. I would not go just for perennials though as a lot die down in the winter. So add a few low growing shrubs or ones that can be clipped like box, daphne, sarcococca, euonymus, hellebores etc for winter interest and don't forget the spring flowering bulbs. Try looking at the RHS website or crocus website for ideas. Crocus also have ready made border designs which you may like.
