HMP Whatton has come out top in a competition to find the best kept prison garden in England and Wales
The gardens were judged by the Royal Horticultural Society.
Whatton placed third in 2011 on also won last year’s trophy.
Whatton’s Governor Lynn Saunders said the prisoners and staff take great pride in the gardens.
She added: “Prisoners help to design and tend the gardens, supervised by the prisons’ horticultural team.
“As well as providing purposeful activity and employment qualifications for the prisoners, the gardens are a pleasant environment for all at Whatton.”
As well as more formal gardens, there are wildflower areas, a wildlife pond and movable pots in hard landscaped areas were planting is not possible.
The prison also grows fresh vegetables for consumption by prisoners and staff. The vegetables are fed using a liquid feed produced from vegetable and garden waste, by four “wormeries” on the premises.
