Veteran gardening presenter Alan Titchmarsh is to design a garden at this year's Chelsea Flower Show, it has been announced.
The project is intended to be a joint celebration of Mr Titchmarsh's 50 years in horticulture and the RHS's Britain in Bloom scheme.
While the garden will not be subject to the RHS's judging regime, it will reflect aspects of the presenter's life.
His garden is to be called 'From the Moors to the Sea – a celebration of RHS Britain in Bloom'. It is to pay tribute to the work volunteers perform in areas of personal significance to the presenter.
It will begin in the Yorkshire Dales, where Mr Titchmarsh was born, and end in the Isle of Wight, where he now owns a home and where Britain in Bloom volunteers work alongside schools and businesses.
He is to work alongside RHS Chelsea Flower Show gold medal winner Kate Gould on the new garden.
Mr Titchmarsh, 64, who is an RHS vice-president, said: "I can think of no better way of celebrating 50 years as a professional gardener, and 50 years of RHS Britain in Bloom, than by creating a garden for the RHS at the Chelsea Flower Show."
Last year, the veteran presenter shocked gardening fans when he revealed he would no longer be presenting the BBC's programming in Chelsea. It later emerged that his replacements are Monty Don and Sophie Raworth.
In 1985, Mr Titchmarsh won a gold medal for a garden he designed for the Chelsea Flower Show.
RHS director general Sue Biggs said: "As the world's most famous and best horticultural event, RHS Chelsea is the perfect place to celebrate both Alan's and RHS Britain in Bloom's 50th anniversaries."
There are now 300,000 Britain in Bloom volunteers looking after 200,000 acres of public land, helping to clean up neighbourhoods while making them greener.
'From the Moors to the Sea' will be located next to the RHS stand, at the bottom of Main Avenue opposite the triangle.
