It's a fairly good book, but the lack of photos makes it hard to follow. Author is very good about using Latin names so readers are all on the same page, but lack of photos makes it difficult to picture the combinations she discusses. Makes important points supporting the theory that heat hardiness becomes as important as cold hardiness when dealing with the Midwest. Some ideas imparted through the book are good for a new gardener to the region who may not have already experienced them. A veteran gardener of Zones 4 and 5 will probably not learn anything new.
