Isabel Bannerman is, in the words of Richard E. Grant, ‘one of the world’s foremost garden designers’. With her husband, Julian, she has designed gardens for King Charles III, for Lord Rothschild, for John Paul Getty . . . and for any number of other grandees and celebrities. But their favourite gardens are those they have made for themselves, notably at Hanham Court near Bristol, Trematon Castle overlooking Plymouth Sound and Ashington Manor in Somerset. Min Hogg, in World of Interiors, describes Isabel and Julian as ‘mavericks in the grand manner, touched by genius’. Isabel’s first book, Landscape of Dreams, in which her writing was described by Anna Pavord as ‘brilliant . . . vivid, engaged’ was The Sunday Times Garden Book of the Year 2016, Scent Magic, (‘a dream of a book’) was The Sunday Times Garden Book of the Year 2019.
