The 10 metre by 12 metre From Freedom to the Future garden is currently being jointly created in Leeds and in South Africa.
The finished garden will reflect both English and South African plant life and the designers are hoping it'll be in with a chance of winning a coveted gold medal at the Chelsea show.
The 2004 show at Chelsea starts on Tuesday 25 May.
After the show is finished the garden will be re-assembled in Leeds.
