HENNESSEY ON ROSES 
Most of the directions for rose care have been omitted from this catalog 
because they have been treated so much more fully, and with all the underly- 
ing reasons for every course of prodecure taken care of so thoroughly, in my 
new rose book, “‘Hennessey On Roses.” Rose growers will profit from omis- 
sion of necessarily sketchy outlines of rose care in this catalog, and a study 
of the full subject together with the “why’s” behind it. 
The book of about 65,000 words, illustrated with numerous photographs 
taken in my own gardens, will be available at the price of $3.50. Send orders 
directly to Roy Hennessey, Hillsboro, Oregon. The book is entirely new, and 
contains innumerable scientific facts behind rose behavior that have never 
been discovered before. It is a book of applied rose scieice made enjoyably 
readable. The book not only discusses all the facts pertaining to a knowledge 
of the rose which have enabled me to produce my remarkable plants (which 
are no accident!), but answers every question that has ever been asked me 
on the rose. Every bit of the book is designed to be applied to your own rose 
garden. 
You won't find anything in the book approached from the conventional 
standards, and only a couple of “theories.” The rest of the material consists 
of rose facts, the knowledge of which enables me to produce Hennessey roses. 
A knowledge of them will enable you to care for your roses with outstand- 
ing results, and you will greatly improve your enjoyment of your rose gar- 
den because you will be in possession of all my knowledge of what makes 
roses do as they do. 
The book is not padded or dated with discussion of existing Hybrid Tea 
rose varieties which would make it obsolete in a few years. Description of 
best modern rose varieties is the function of this rose catalog.
