Great British Garden Revival

Toby Buckland wants to bring back scent to our gardens, visiting a scented garden at Kenilworth Castle which was originally created to win the heart of a queen. He holds the country's first ever scented flower competition and gets behind the science of scent when he meets a chemist and perfumer in the Cotswolds. Tom Hart Dyke wants to convince us all to grow tulips. He visits Spalding, which used to be the heart of tulip growing in the UK. He discovers the turbulent history of the broken tulip which four hundred years ago brought an economy to its knees, and lends a hand to one of Britain's last large-scale commercial tulip growers in Norfolk.
