This book has some excellent color photos of the plants. It contains some 1247 color photographs, 1219 ranges of where in the Pacific Northwest you would be likely to find the plants. It covers some 1200 species. This is an excellent book but with some faults. It makes it easy to find a flower by organizing the flowers by color, number of petals and shape of the blossom. The range charts make it easy to know where they should be normally be found.

However, the index is somewhat strange. The index is organized by the complete name. That is to say if you know the plant by its group such as Monkeyflower, you can't find monkeyflower in the index. You can and must know it is a "Mountain Monkeyflower" and find it under the letter M or under an O for "orange bush Monkeyflower. In fact there are no less than 29 flowers under "Mountain" something. You won't find "Buttercup" you have to know what kind of buttercup and find it under "W" for "Western Buttercup." In fact there are 61 flowers listed under "W for "Western something." Why they didn't list all the buttercups under "B" as well, is strange. The book is quite useful if you don't know the name because it is easy to find a four petal white flower. To use the index you must know what lily it is. You can't jut look up "lily."
