Monty Don and Joe Swift take a tour of the trailblazers and trendsetters from the most famous flower show in the world. Every year, Chelsea leads the way in showcasing the latest ideas in garden design and the newest must-have plants. Joined by Carol Klein, Adam Frost and the team, Monty and Joe examine how technology has influenced our gardening habits and meet the fresh talent who are breathing new life into this traditional event. We find out what inspires fashion designer Paul Smith at the show year after year and relive the designs that challenge our notions of what gardens can be.
