Chris Bavin meets a group of extraordinary Bloomers who must start from scratch every year after their gardening efforts are literally washed away. Tewkesbury in Gloucestershire is at the confluence of four rivers, which makes for a lovely setting, but one that devastates the town to a greater or lesser degree every year when the waters rise and flood the town.

Chris Bavin meets the Chorley volunteers, who have been competing in Bloom for 15 years and are gold winners. This year major construction work in the town centre is proving a massive challenge for the group.
