Have I blundered into a history site ? 
Have reluctantly dog-walked. Took them for a browse round one of the larger garden centres near here. Saw some strange potted bushes, only about 18" high with lots of close-together buds. Had no clue what they were - turned out to be tiny peach trees!Need a new foldable pruning saw, they didn't have any, and need a few bits of trellis to replace the rotting falling-over pieces in the raised bed by the front door - pricey. Still, nice to have a potter.
