The 67-year-old royal headed to Green Park in central London to mark the creation of The Queen's Meadow, which is part of his Coronation Meadows project and named after his mum, Queen Elizabeth.

A series of posts on the Clarence House Twitter account read: "The Prince of Wales visited Green Park in #London today to celebrate the creation of The Queen's Meadow.

"The Queen's Meadow is part of HRH's wildflower project, which aims to create a wildflower meadow in every British county.

"The Queen's Meadow has been named in honour of Her Majesty The Queen's 90th birthday. #Queenat90"

Charles' brainchild started in 2013 when Queen Elizabeth, 90, celebrated the 60th anniversary of her Coronation.

In 2013, Charles said: "My Coronation Meadows idea came to me when I read Plantlife's 2012 report and fully appreciated just how many wildflower meadows had been lost over the past 60 years.

"This year, we are celebrating my mother's coronation so surely there is no better moment to end this destruction and to stimulate a new mood to protect our remaining meadows and to use them as springbokards for the restoration of other sites and the creation of new meadows right across the UK."

Charles is known for his horticultural work and has concerns about the impact of climate change and global warming.

In July, he became a patron of the Royal Botanic Gardens at Kew and admitted he was "delighted" to be an official supporter of the gardens.

He said: "I have always had the greatest affection and admiration for the Royal Botanic Gardens at Kew, so I could not be more proud and delighted to have been invited to become Patron of this great institution. Kew has had its roots planted deeply in British soil for more than 250 years, but has developed an international reputation as one of the world's greatest botanic gardens, renowned for its scientific research and plant collections."
