The history of the English garden reveals more than expected about the past and its people. This series explores the theme of gardens as places of work, rest, and leisure.     In this talk award winning garden designer Anne-Marie Powell talks about mental health, horticulture and happiness. This talk was recorded live at Hampton Court Palace in 2015.  For more information on the history and stories of our palaces visit: www.hrp.org.uk/history-and-stories
