South America - S1.E4

South America, almost twice the size of Europe, is a continent with the most diverse climate and range of landscapes on the planet. It's also home to more than 50,000 endemic plant species but is a land under intense ecological threat.

Monty starts his journey in Rio de Janeiro to see the private garden of Brazil's greatest artist, Burle Marx, before travelling by boat to the ingenious floating gardens of the Amazon. He also takes in a crumbling traditional 'estancia' in the wind-swept Pampas, before finally ending his journey on the craggy Pacific coast of Chile where one man has created a garden completely in tune with its landscape.
