In this episode, we join the King at the annual Chelsea Flower Show where the pressure is on to create a garden in his honour, and meet the legendary party planner to the royal and rich, as he creates a lavish millionaire's party. We go behind the scenes at the hair salon trusted by Kate Middleton on her wedding day, and we're at the Royal Borough's car dealers, where cars go for twice the price of the average UK house.Every spring, the historic – and peaceful – Royal Hospital Chelsea becomes the busiest place in the borough, as it plays host to the world-renowned Chelsea Flower Show. This year, there are 36 feature gardens, with the most prominent of all to be created by horticulturalist Dave Green. He's been commissioned to create a garden that both celebrates the new King, and commemorates the late Queen. It's a huge honour, but it comes with huge pressure. Dave has been in contact with the gardeners at Sandringham to get the choice of plants just right. But will it be enough to win the approval of the King when he visits the Flower Show for the first time as monarch?If you're organising an event in Kensington and Chelsea, there's just one man to call on: legendary ‘party architect' Johnny Roxburgh. He's produced many a royal party, including Prince William's 21st. Now he's organising a party at the Chelsea Physic Garden for a local multimillionaire, and it needs to be planned with military precision, with gourmet canapes, a stunning marquee and vast floral arrangements. Every waiter will have a customised outfit inspired by French fashion designer Jean-Paul Gaultier, and there's even a dedicated make-up area where the waiting staff are primped with fake tans and tattoos.
