If you're the green fingers type you will know all about the annual Chelsea Flower Show, if you're not, it's loads of really pretty flowers in short, and a lot of posh folk. Monty Don and Joe Swift will launch BBC Two's week of programmes from the event, which will also feature coverage of the Queen's annual visit. They also look forward to tomorrow as they reveal which designers they think will scoop the top prizes. And just in case the whole thing couldn't get any MORE British, Sherlock star Benedict Cumberbatch and his actress mother Wanda Ventham share their favourite Chelsea moments. Splendid.
