Alan Titchmarsh presents a stunning series that reveals the amazing secrets behind Britain's great gardens, examining how they continue to influence gardeners, including himself, today. The Victorians gave us a taste for exotic plants from around the world, a thirst for technology in the garden and a love of bold statements. Biddulph Grange, in Staffordshire, is a classic example of all these elements. The Victorians were transforming the garden from the natural landscapes of the 18th century to a new manufactured style. Alan comments how Biddulph is 'a world in one garden' made up of separate highly stylized designs inspired by China, Italy, Egypt and Scotland. These gardens are a setting for plant life from around the world and Alan explains how the Victorians were passionate plant hunters, particularly for orchids. He also shows us how to plant and care for exotics in our own garden. The Victorians also invented ways to transport and care for these rare plants. Alan demonstrates how they revolutionized growing under glass, building some of the biggest glasshouses in the world. There was also a passion for elaborate and gaudy display at this time with the creation of the carpet bed - a true symbol of Victorian knowledge and power. Alan shows us how to create one that will complement our own modern garden. A passion for technology was also transforming the kitchen garden and the Victorians established practices for produce growing that survive today. Alan reveals the key things to remember when growing vegetables.
