Mr Herbert was met ahead of the tour by Reverend Sara-Jane Stevens and her husband Bob.
Sara-Jane praised the community effort which had helped to transform the church for the festival with the theme ‘A Walk on the Wild Side’.
Mr Herbert said: “I really enjoyed seeing the church transformed in such a charming way. The displays were wonderfully creative.
“It was also a pleasure to meet the Reverend Sara-Jane and Bob who are so obviously enjoying being a part of the Thakeham community.”
The floral exhibits were produced from flowers grown in the village and the displays incorporated artwork and installations.
One area of the church included a water-feature surrounded by foliage and flowers.
Unusual items such as old footpath signs, beehives and stuffed animals were included in other displays.
The annual three-day festival and open gardens last month included evening events and entertainment.
All proceeds from the festival will be shared between St Barnabas House, St Mary’s Church and Jubylee Bakes – an award-winning bakery run by a group of adults with special needs, based in Thakeham.
