My first ever cottage garden is looking fab at the moment. However, sme of the bedding is starting to go over and perennials moving towards jaded. So what do I plant now to give some autumn colour? I have light well drained raised beds and a blue/purple/white theme going on with digitalis, eryngium, hydrangea, and clematis. My gladiolii is yet to flower. Full sun for some part shade for others. Any Ideas?
