I like her and Christopher Lloyd's Dear Friend and Gardener. HE Bates was a good garden writer, A Fountain of Flowers for example. I have to be in the mood for reading about gardens, I do wish I had kept a record of those I have read as I never remember the titles of books or who wrote them. I read a lot, but when it comes to gardening books I am more likely to read my way through the RHS's Encyclopaedia of garden plants than a story of how a garden was made.
Beth Chatto's gardens are indeed incredibly beautiful, if you can get there in early June when all of the climbing roses are scrambling through the immense trees it is spectacular. I was lucky enough to meet her a couple of years ago, I was taken there by a friend who was taught by her when she was a florist, and they have stayed in touch. She is getting on a bit now but still lives there and still won't let them plant any new plant without her sayso! It's immaculate.
