The parish won Floral Guernsey 2009 to be nominated for Britain in Bloom
Twelve months after they picked up the top prize in Floral Guernsey 2009, St Pierre du Bois was judged for Britain in Bloom 2010.
The parish spent the year leading up to it by starting several new projects and developing old ones further.
Andrew Jackson and John Woodward, who judged the parish, said: "The main thing we've seen is the community involvement has been fantastic."
The parish fell into the large village category with six other places.
The judges explained that community is now an important factor in the Britain in Bloom competition, counting for up to 25% of the entries overall score.
They said: "The local school, local businesses and local community groups have all been involved in the campaign here and that's marvellous - it's a true community campaign."
The scheme saw parishoners of all ages helping out
Andrew and John only had an hour in the parish to see as much as they could: "I wish we'd had more time - we met some fantastic people on the route."
Amongst the projects the parish undertook in 2009 and 2010 were a
major tree planting project
alongside the BBC's Tree O'Clock project, which saw more than 100 trees planted in the rectory walk.
Another project involved
screening a bank of clay at the L'Eree Aerodrome with hawthorn trees
to help the area's natural wildlife develop further as well as improving the area's aesthetic qualities.
Part of the parishes' community work involved asking resident to donate an hour of their time with the Give An Hour Scheme, to work on the floral aspects of the parish.
On judging day the parish showed off the field near the church, which included part of the nature trail they have developed in recent years, with a community day including games, storytelling and food all provided by parish residents.
The winners of the Britain in Bloom awards are due to be announced at a ceremony at the end of September.
