Career: De Thame had a successful modelling career that saw her appearing in a number of TV advertisements. Her casting agents started suggesting her for acting roles and, in 1998, she appeared in the mini-series Merlin. She decided not to follow an acting career, however, and decided to get into plants and gardening instead. After studying practical horticulture and plants and plantsmanship at the English Gardening School for two years, De Thame auditioned for Gardeners' World. She initially presented the programme every week and, as of 2014, continues to make occasional appearances on the show. De Thame has also presented such TV gardening shows as Small Town Gardens, Gardening with the Experts and Countrywise. She also co-presents the BBC's annual coverage of the Chelsea Flower Show. Her non-gardening TV appearances include Going for a Song and Call My Bluff.
