The Prince of Wales has attacked critics who refer to him as a "potty" royal but has admitted he talks to trees and plants as if they were his children.
In a candid interview for a BBC documentary, Prince Charles dismisses suggestions he is "loony" but confesses to lying on the floor at his Highgrove home to eavesdrop on visitors.
He tells the presenter, "I got a lot of flak for a lot of things. I mean, bewildered, frankly, as though you were doing something positively evil. I mean potty this, and potty that, loony this and loony that."
But he confesses, "I have eavesdropped on what the visitors have said."
He describes speaking to shrubbery as something which keeps him "relatively sane." "I happily talk to the plants and the trees, and listen to them. I think it's absolutely crucial," he is reported to say.
Underlining the importance of his garden, he adds, "Everything I've done here, it's almost like your children. Every tree has a meaning for me."
The Prince, who is widely known for his devotion to organic farming and environmental issues, adds, "Terrible thing really, mustn't get too attached. I shall have to try and detach myself soon, psychologically."
