The local pizza place does a great job of saving 10-liter buckets for me. The buckets would otherwise have gone to the dump. Strange state of things, that we produce buckets for use during a few days and then feed them to the furnace. Anyway, the pizza place sets them aside for me, and I am very happy to use them in the paved areas of my urban garden. Many of them go to the potato farm, that not only gives us potatoes to eat, but also the opportunity to enjoy their beautiful flowers! Exquisa, Blue Congo and October Blue are flowering at the moment.
