The Chelsea Flower Show is an institution in Britain amongst dedicated gardeners. For one week in May, the cream of the countries garden designers descend on London to show off their skills, but this year something a little odder has landed. "600 Days with Bradstone" is the title of a garden designed by Sarah Eberle for a 600 day stay on Mars, and it's scooped the top Gold award for 2007 and "best in show." Sitting beneath an imaginary dome, the garden is divided into two distinct parts. At one end of the garden is a section designed to draw water from the Martian permafrost; at the other a section designed with the mental well being of the astronauts in mind. The design of the garden has been closely modelled on Mars, and even the plants have been picked for their likely survival properties in the harsh Martian environment. Alas all the tickets are gone, but for more detail on the winning garden, you can visit the website of the Royal British Horticultural Society or take a look at the official 600 days with Bradstone website.
