Query: Everything you need to know about the cultivars.

I am in the green indusrty and this book has always been the bible. I just have never owned one. But A. palmatums and their many cultivars are becoming more and more available even at the retail level. This book will identify any a. palmatum you will find at a local wholesale or retail nursery. Great photos and descriptions.
