Initially, the garden tour in England and Wales involves private gardens and gardens that does not accept visitors regularly under the National Gardens Scheme, when "Gardens of England and Wales Open for Charity" (the 'Yellow Book') served as a guide book for those seeking to visit gardens in England and Wales.[1] The first issue of the Yellow Book was published as a supplement to a British magazine "Country Life" in 1931, after Elsie Wagg of an institution serving for district nursing came up with the basic idea of National Gardens Scheme, in which a charity and garden tour was combined when gardening was quite popular in the UK.[2]
