Anthea Guthrie, who has previously won four gold medals at the world-famous show, created this 1940s inspired garden with the teenage boys from special needs schools Heronsbridge and Ysgol Bryn Castell who she has been working with for two years.

The piece, called A Child’s Garden in Wales, features toys made by the students, including a newspaper and string football and hobby horses made from Welsh wool socks.

A 1940s Amateur Gardening magazine has been recycled as biodegradable flower pots, a dog kennel was created from a barrel and there’s a doll’s pram used to gather waste coal from the pit.

The garden also features Virginia stock, marigolds, and love in a mist – all typical of the kinds of flowers children would have been given to grow at the time.

The group got their inspiration after a trip to St Fagans National History Museum in Cardiff, and have used 1940s gardening books to meticulously research the techniques and the features typical of a garden from the era.

Ms Guthrie said: “The inspiration for the garden came from the children. It’s been an ongoing project since September. The kids have done a lot for the garden. We have made a lot of things from scratch. There are 1947 flower pots which they created and there is a football made from newspaper and string, which people used to do at the time.”

The garden includes a rusted iron junk fence with umbrella spokes, bits of old bicycle, an advertising sign, a coal cinder path and a rake.

Ms Guthrie added: “It’s great for the children to get the experience and the garden has been really well researched. The children can learn about history as the piece ties in with the coal industry. We have also had items donated by St Fagans and we have a mug from the First World War that was given to every child at the time. We have just been collecting things as we go along. I’m really pleased with the finished result. The kids are coming today and they are really excited. I have been teaching the group for about two years. It’s particularly nice for boys to be interested in gardening as children are the future of agriculture.”
