To celebrate British Flowers Week, Charlotte Smith and Anita Rani look at the resurgence of British flowers. Charlotte meets a Hampshire farmer who has diversified into British blooms, with as many acres given over to flowers as to food. Charlotte is intoxicated by their fragrance and finds out what it is about the smell of flowers we find so bewitching. Anita Rani visits Covent Garden Flower Market, where she meets the traders doing a roaring trade in roses. Meanwhile, Matt Baker takes to the old pack horse trails through the New Forest and hears how the ponies were used by smugglers to ply their illicit trade. He also visits a farm where water buffalo are the main livestock. Adam Henson gets stuck in with the sheep shearing and hears from farmers about the prices they get for their wool. Tom Heap investigates why areas set up by the government to protect our seas are being branded by some scientists as worse than useless.
