You would think even those lacking a green thumb could keep cacti alive, but for the most helpless of gardeners, Eric Carroll's Desert Steel sculptures are a saving grace. The galvanized steel is guaranteed not to corrode, and the verdigris patina is amazingly realistic. Some models incorporate torches (flaming saguaro, anyone?), and if you're willing to shell out the big bucks, you can even plant a steel palm tree.
