No Green Thumb Required

Everybody’s talking about “green” gardens, but you can’t get much greener than the planting that Marie Christophe created for this outdoor space in Paris. You don’t have to water her wire sculpture, and you don’t have to take care of it. The real beauty of it is that it grows not up or out but on you. OK, if you’re a traditionalist who can’t see your way to leaving it plain, you can train a vine to climb up its lovely form.
