This book was one of many books on my list of books need for my Master Gardener course at the UofA Devonian Botanic Gardens in Alberta. It was also the most costly book I had to get, but it was certainly by far the best book. I've used it over and over again, not just for my course but also for friends wondering about some of their plants. It has EVERYTHING you could possibly want from a plant ID status. For example, height & spread, pests & diseases, Alternative names, origin, propagation just to name a few.
If you need an book with every possible Canadian plants then this book is for you! Don't worry about the price because in my mind this book should be selling for 2 or 3 times more than it is. It's well worth it!
