The RBC New Wild Garden at the RHS Chelsea Flower Show 2011 - Silver-Gilt Medal Winner

Led by award-winning landscape designer Nigel Dunnett, the RBC New Wild Garden was the RHS Chelsea's first full-scale "rain garden", designed to capture and use every single drop of rain that fell on it.

The same team also collaborated on the recently-opened RBC Rain Garden at the Wildfowl and Wetlands Trust (WWT) London Wetland Centre as part of the RBC Blue Water Project.

The RBC New Wild Garden brought together two major themes in British gardening in the last 100 years: the Arts and Crafts ideal - celebrating the artistic and painterly use of plants, combined with high quality and traditional craftsmanship, local materials and strong sense of place - and the wild garden - celebrating the beauty of nature, and the naturalistic use of garden plants.

The rain garden element was in keeping with the goals of the RBC Blue Water Project, a wide-ranging, 10-year global commitment to help protect the world's most precious natural resource: fresh water.
