This is a beautiful book, not only in it numerous colored photos but in the information it gives. Each different group is thoroughly explained. Most of the book is geared toward guiding you in choosing plants from each of the groups to help you have flowering throughout the year, as much as that is possible for your area.
Also talks about where clematis can go in your landscape, pruning and care. Along with photos to show examples for all of these principles.
I am new to clematis and am just thrilled with what I am learning reading this book...along with the beautiful photo to savor! I couldn't find the book that I had gone to the bookstore for, so got this one instead! So glad I did.
