Too much repetition. For each entry: If you have problems, your local plant dealer can give you advice. Well, often the advice you get is not accurate. Lots of references to what his granny grew. It's great he loved his granny, but that is folksy and not useful information. Ignores the problems with periwinkle and red tip photinia diseases.Pictures are very good. Book is well organized. Bibliography leaves out some important other books by competing radio call-in hosts.I get the impression that Mr. Groom is a nice, well-intentioned man, but this is not a definitive work on Texas decorative gardening.
