It's the Prince versus the prisoners at the Chelsea Flower Show.

The Queen was at Chelsea on Monday viewing the show gardens.

Among them is one inspired by her son's estate at Highgrove, and another grown and built by inmates of Leyhill Open Prison.

Both the Prince of Wales, with a garden inspired by a carpet at Highgrove and the prisoners of Leyhill will be hoping for a gold medal.

Leyhill won gold last year: but what does gardening do for those in jail?

Is it what we expect prisoners to be doing with their time inside?

Miniature Eden

Leyhill Prison's show garden is a version of the Eden Project.

Water flows through a transparent dome and there is a miniature rainforest inside.

Around the sides Jeff Groundrill, head of activities at the prison, has supervised a team planting everything from tea plants to potatoes, mustard and sweetcorn.
