It is March and Ruth Goodman, Alex Langlands and Peter Ginn greet the long-awaited arrival of spring. It is time to bring in the daffodil harvest. During it's heyday in the early 20th century, the Tamar Valleywas the largest producer of early daffodils in Britain - the result of the region's mild climate combined with the arrival of a railway, which meant produce could be delivered to towns and cities across Britain within hours of being picked. The team takes their daffodil crop to the train station and gets to grips with the workings of the Edwardian steam-powered railway system.
