Query: Love this book!

I love this book! It had a lot of great info for any gardener that suffers from pollen allergies (or cares about family and friends who may be suffering). I just wish that the index of plants was more extensive but I understand this would be very hard to do without getting huge and cumbersome. It does, however, give you tips on how to make smarter choices when selecting plants that was very helpful! Definitely worth the cost and I will keep this book around for a very long time for reference.
