I have most of Lois Hole's books being from Canada myself, and her perennial and tree and shrub books were the first "real" gardening books I bought. When I jumped headfirst into perennial gardening about 5 years ago, I bought this book because of its straightforward approach. It doesn't overburden the beginner with highly technical information, but presents useful facts about a great variety of perennials. Small columns about height, colour and varieties, when and how to divide, how to grow and how to propagate each perennial are accompanied by close-up colour photographs. The latin name and/or other common names appear in smaller text at the top of each entry. Although I have now graduated to the technical, encyclopaedia type of reference books, Lois Hole's book will remain a treasured (and still often used) member of my perennial gardening library.
