Percy Thrower
From Tardis Wiki, the free Doctor Who reference
Percy Thrower was a television presenter in the late 20th century, well known for hosting Gardeners' World, which he hosted until 1977.
By 1987, Nora Wicker was a fan of his work, but admitted he had not appeared on TV in ten years. (AUDIO: The World Tree)
Behind the scenes
In real life, Percy Thrower presented Gardeners' World from 1969 to 1976, not 1977, making Nora's guess of 'ten years' an approximation.
