A bit like an animal rescue centre but for plants, the team behind Farmopolis have saved tens of thousands of plants from the Chelsea Flower Show and planted them on a jetty on the Thames in Greenwich. But it's not just a pretty floating garden - there's a cafe and bar here too, and there'll also be heaps of events to go to. These include theatre for kids, literary salons and workshops to teach playwriting, as well as crafts lessons for crochet, wood carving and hat-making. It's open throughout July and August.
