After seven decades exploring the world’s wildest places in search of exotic animals and plants, Sir David Attenborough turns his attention to Britain’s gardens. We may not realise it, but our backyards are home to thousands of species.

Over five episodes - set in five very different gardens across the UK - Sir David reveals the lives of the often charming, occasionally daring, always secretive animal characters that inhabit the hidden world right on our doorsteps. Theirs is no cosy existence - even in these beautiful and seemingly genteel surroundings the rules of the wild still apply.

From pine martens in the Western Highlands to dormice in south Wales, swallows in the Lake District to otters in Oxfordshire and blue tits in Bristol, the series reveals not just a rich and surprising diversity of life but also how each species finds its own way to live alongside us.

And through meeting the gardeners that have created these wild oases, we discover how our nation of animal lovers and gardeners can do their bit to save struggling species. Eighty per cent of Britons have access to a garden, and together they cover an area greater than all of our national nature reserves combined - so our approach to gardening has an impact not only on the animals that live there, but also on whole populations.

You’ll never look at your garden in the same way again.
