Monty Don travels the world in search of the greatest gardening treasures, looking at how they integrate and harmonise with the landscape and the plants that have been chosen.

'If I have learned only one thing from my travels around the world it is that no garden is an island. Context is everything.' Monty Don visits each continent in this landmark series on gardens of the world. Monty digs below the surface of each garden as a decorative space and uncovers its hidden past and significance. He looks at how each garden is connected to the climate, geology, flora and culture of the place, and he tells the tales of plant hunters and spice traders who brought many of the exotic plants, such as rhododendron, Moroc rose, Azalea and Dahlia, to our shores. He visits places as varied as the winter ice gardens of Russia, the Aztec terraces of South America, the Alpine flower meadows of New Zealand, a fusion garden in Australia, the street gardens of Havana and one of the grand aristocratic gardens of Europe.
