The town, headed by volunteers of Stroud in Bloom, and supported by the town council’s Green Spaces team, received the top honour in the Heart of England regional awards for the third year running.
The judges praised the welcome they received from members of Stroud in Bloom.
They called Stratford Park, which is maintained by the Landscape Group under contract for the district council, the “jewel in the town’s crown”.
The town’s “Adopt a Plot” initiative which encourages people to look after unloved pockets of land won plaudits with special mention of the “Ann Creed” plot in Nelson Street.
Judges highlighted: “the volume of teams, businesses, public and private sector teams, and the positive way that they embrace the “In Bloom” way of partnership working”.
Stroud in Bloom chairman Malcolm Tarling said it was very much a team effort with the town, district and county councils as well as the Stroud Chamber of Trade and community groups.
“It was the group effort that achieved this wonderful win from the people who pick up the litter to those who put out that extra basket. It all counts and makes our town far more attractive to visitors and residents.”
The Lord John pub received a silver gilt certificate and the Crown & Sceptre received a gold for its floral displays.
“The judges praised our wildflower areas, the new mural in the Shambles and the involvement of Stroud Valley Project,” said Mr Tarling. “Our traders did us proud and we hope even more will join our campaign next year.”
