John removed a bunch of brambles from one end of the shrub border a summer or two ago by scraping them off the face of the earth with the bucket of the tractor. Now a great clump of foxgloves has volunteered on the spot! There are a lot of foxgloves sprinkled around the hill, but I didn't realize they would lie dormant in the soil, awaiting their chance at conquest. This makes me want to go around experimentally scraping places here and there to see what happens. Sure, you might get yellow dock and pig-ear plantain, or you might get extravagant columns of pink and white bells!
