Chelsea garden to use every rain drop

This May's Chelsea Flower Show will feature its first full-scale sustainable "rain garden", inspired by Victorian horticulturalist William Robinson.

The RBC New Wild Garden is designed by Dr Nigel Dunnett to use every drop of rain that falls on it. The central building, a shipping container, will have a "living roof" and drainage and water collection pools reuse rainfall. Robinson's 1870 The Wild Garden introduced "naturalised" planting.
