Ellie Harrison takes a look at the part flowers and plants play in people's everyday lives. She visits a herb garden in Bristol to find out about a commonplace plant that's on the front line in the fight against cancer. She heads to a high-end restaurant to hear about the latest foodie trend, fermentation, a kind of turbo-charged pickling. She meets a dye maker who's turned her back on synthetic dyes and uses only natural plants and flower dyes to create her colours. And Ellie also visits the school where pupils cultivate some of the rarest orchids in the world.
