I use several for reference, but most often reach for:
Roses for the Scented Room, Barbara Milo Ohrbach
Old-fashioned Roses, Orietta Sala
Roses, Orietta Sala
The American Rose Society encyclopedia of Roses
American Rose, magazine for the ARS

With so much info available on the internet, books I don't use much anymore go into rose society raffles or book sales. I used to pour over the big Botanica's but don't think I've even thumbed through it in 2-3 years.

Horizon Roses -- it gives fantastic information on newly-released roses with exhibition potential.

I second the recommendations for Landscape with Roses by Jeff Cox and The Rose Bible by Rayford Clayton Reddell. Passion for Roses by Peter Beales is also good. I also like The Ultimate Rose Book by Stirling Macoboy as a coffee table book. My favorite of all of them is Landscape with Roses for its readability and beautiful pictures.

100 Old Roses for the American Garden

A Rose Odyssey by J. H. Nicholas, 1937 if I remember correctly.

Roses, Jack Harkness, 1977, Dent Publishing.

Rose Growing Complete, 1970s, E.B. LeGrice, the paperback one, not the 1965 hardback.

The Makers of Heavenly Roses, Jack Harkness.

For a REAL romp, not just for the knowledge it imparts, but also because it was written by THE most opinionated curmudgeon ever, Hennessey on Roses, Roy Hennessey. As a condition of selling you his roses, you had to promise NOT to cut the roots! The dedication he wrote to his long-suffering wife says it all! Lots of valuable information, historical information and absolutely hysterical in his "absolutes"!

Papa Floribunda, the Gene Boerner Story

My Life in Roses, by Herb Swim.

1920s through early 1940s ARS Annuals. Full of lovely articles written by rose luminaries of the day, many of whom you have heard of, some you haven't. Wonderful historical information about people, gardens and varieties you can still find from specialty sources.

All of which impart a great deal of good, practical information, tremendous historical information and a lovely level of "the romance of the rose". I loved them all. Kim

100 English Roses for the American Garden
200 Tips for Growing Beautiful Roses
A Year of Roses by Stepeh Scanneillo

Ronda, if you are looking for something that is out-of-print, e-mail me. I am wanting to sell my rose books can't afford an Amazon Account.

(I've done my rose passion (i.e. Shows, Good friends with the Bernadella's, conventions and lots of roses) ready to hand down the passion.

I have to second Jack Harkness's Roses, which I think is the best rose book ever written. I have also reread Scanniello's Year of Roses many times. Neither book sports many pictures.

For rose porn, check out Quest-Ritson, or Macoboy, or Botanica's Roses.

Ladyrose, Amazon doesn't charge you to post books for sale -- they take a cut of the sale price, but they don't operate like eBay does. List a book, and it will stay there until it sells with no cost to you.
