Only joking. I'll second andrews selection and add Herbs and Lavender to to the list as these will have a more intense scent due to being baked. Also try looking at the hardy annuals as thes won't mind the poor soil conditions. Just make sure you have drainage in the wall otherwise you'll just have a long narrow bog garden
