Carol Klein reveals that she is daft about daffodils. On her revival she uncovers the history of the UK daffodil industry on a visit to Cornwall's Tamar Valley, takes to the streets of Falmouth and paints the town yellow, and meets a specialist bulb merchant in Somerset. Chris Beardshaw is on the blossom campaign trail. On his revival he visits a man in the Scottish Borders who has restored a walled garden and created a living library of heritage fruit trees; takes to his bike on the blossom trail in Worcestershire; and meets a woman in Edinburgh who has been campaigning to save the flowering cherry trees on her street from the chop.
