Viviane de Faitaud has grown up alone at her family's château, for her father, the Marquis de Valaine, lives at the court of Louis XVI in Versailles. After a hailstorm destroys the château's orchards, gardens and fields, an ambitious young Welshman, David Stronach, accepts the commission to plan new gardens in the hope of making his name as a landscape designer. However, the love that blossoms between them is doomed: Viviane is betrothed to a duke, and David is forced to leave the property. In the aftermath, Viviane enters an unhappy marriage and moves to Versailles, while David embarks upon a mission to China to procure the secrets of tea-growing. There, he is inspired by the story of the Blue Rose, a fable of impossible love. Can he and Viviane – a world apart – ever hope to rekindle what they had together?
