I was talking to someone the other day and they were asking me if I knew of a book that they had seen in a shop and wanted to buy. The assistant didn't know the price of the book and so the person I was talking to left it with the assistant to find the price whilst she looked for other books. When she came back to the counter another assistant had sold the book to someone else. Unfortunately, no one could remember the title or author. It seems the pages were divided (physically) into three strips so that the images of the plants/garden areas could be mixed and matched to generate ideas, give an idea of what goes with what etc. I had a dim memory of seeing either this book or a similar one sometime in the past. Does anyone know of the book, maybe it's title or author?
