Prince Philip sent a letter to TV presenter and gardener Alan Titchmarsh, to tell him about the work he had conducted in the parks of royal residences.
Titchmarsh appeared in the BBC’s coverage of Prince Philip’s funeral at Windsor Castle on Saturday 17 April.
Prince Philip told Titchmarsh that he enjoyed the book and then proceeded to list everything he had done in the home park, including the avenues he planted.
The late royal had two different ways of looking at a person, according to Titchmarsh, either with “a twinkly eye or beady eye”.
