The competition will be held at the RHS Flower Show at Tatton Park on 23-27 July 2008.
Preston City Council won gold this year with its Wallace and Gromit-themed flowerbed. Head of horticulture Jim Park said the award created many benefits for the council: "It's great for staff morale and we are able to test out growing and planting skills against other authorities. Our gold medals have raised the profile of the department, which have helped us to argue our case when working out budgets."
Our design got good coverage for Preston council because there were ads for the TV programme around the city at the time. We couldn't have bought that advertising. Our three gold medals have raised the profile of the department which have helped us to argue our case when working out budgets."
