Watch Around the World in 80 Gardens online: Episode 2 Australia and New Zealand

Monty travels to two of the youngest gardening cultures in the world. But it's not just about dreamy climates and wonderful plants. Monty sets out from the aptly named Botany Bay to uncover a story of culture clash and invasion, where the gentle habits of the indigenous people and the extraordinary natural landscapes have been dashed aside in favour of imported plants and a very 'English' garden style. In New Zealand, he sets off in search of the wild heart of the country, where he revels in a magical rainforest garden created entirely of native plants. Gardens: 8.
