When Griselda, newly returned from Hong Kong, set out to rescue the ‘dismal-looking’ plants in her garden, she looked for a general guide book to help her – and failed to find one. Instead, she started to collect information wherever she could.  After twenty years of gathering gardening knowledge, and testing it out in her Derbyshire garden, she has put together the book she wished she had access to then.  (Extract from publisher The Pimpernel Press) ISBN 9781910258231
