Team Green Moor, a group of committed volunteers who meet in all weathers to make sure the village looks its best, won a gold at the national awards show and also came out top of the small village category - which they believe is a first for any group from Barnsley.
Team member Claire Derrick said: “It’s a tiny village but people have put in an awful lot of work, thousands of hours have gone in and this is the reward.”
The theme for this year has been the area’s history and heritage - quarrying, the saltway trail, farming and Wortley Top Forge.
Displays in the centre of the village - with a population of 190 and no pubs, schools or shops - and its gardens have reflected this.
The RHS judges said: “This community, by working together, have embraced the Bloom ethos and celebrated their tiny village in a variety of ways that were both a delight and surprise to the judges.
“Team Green Moor should be justly proud of their achievements.”
