If you're looking for ideas to add spots of interest to your garden, particularly as the summer progresses and your garden looks a little tired, try this: dig up some of those perennials seeding themselves everywhere right now and pop them into clay pots. Keep them in a shady spot for a few days so they can get used to the shock of having been dug up, watering all the while. Here is some ornamental sorrel (which is an absolute bugger to control - it seeds itself while you're not looking), some Creeping Jenny, a little feverfew, and some Irish moss.
Oh no. Another goal for Germany. Sob.
