This work, published previously by the American Rose Society (ARS), represents a listing of all officially registered rose cultivars globally. It will supersede the previous edition, Modern Roses X, published in 1993. Modern Roses XI contains descriptions for more than 25,000 roses. The book features 28 color plates and includes a CD-ROM of the entire work which makes searching easy.

Eighty varieties of roses are pictured and described here, with planting instructions and growing tips. Hardiness, disease resistance, fragrance, size of blossom, and blooming season are noted for each. 80 color photos.

Each registered rose name entry includes the ARS classification, color class, year of registration, synonyms parentage, hybridizer, introducer, awards, and a brief description. Abbreviations and entry explanations are given on the endpapers. Appendix III is a directory of hydridizers, introducers, nurseries and others involved in the rose registration process.

The rose is the quintessential flower of the summer. This practical guide includes an introduction on how to use modern roses to the best advantage, a plant catalogue and a grower's guide with everything you need to know.
