"Staffordshire University graduate Nigel Matthews was commissioned by Stoke's British Ceramics Biennial to design and make a ceramic feature to be used in the show garden which includes a six-foot run of ceramic flowers."
There will also be a central bottle-kiln shaped greenhouse. Sponsors include Johnson Tiles, The Trentham Estate, and Bartholomew Landscaping.
Not quite sure what the little guy in the bottom of the picture is doing. Braining himself with a trowel? :)
