From the Royal Botanic Gardens, Kew, Unearthed returns — celebrating 25 years of the Millennium Seed Bank at Wakehurst, the most biodiverse place on our planet.
Hosted by Cate Blanchett, Kew’s ambassador for Wakehurst, this series explores the story of the world’s largest wild seed bank — a vault and living laboratory where science and conservation meet. From restoring habitats to protecting biodiversity, these seeds hold the promise of our planet’s future.
This is no distant insurance policy. It’s one we’re already relying on — and one that will only grow in importance as our climate changes and biodiversity is lost.
As the Seed Bank marks its 25th anniversary, Cate discovers how its groundbreaking work is already shaping life on Earth — and why its mission has never mattered more.
