Roses have been always among the world’s most favourite and admired flowers because of their unusual beauty. The study was conducted at the `Super Rosa Csiki` Association located in Ciumbrud, Alba (Romania), nursery in which annually, many valuable cultivars from abroad are grafted, for economic purposes. The research focused on the evaluation of phonological behavior and main morpho-decorative characters regarding 10 Rosa hybrida cultivars namely: 'Acapella – Tantau’, 'Caprice De Meilland ', 'Imperetrice Farah', 'Burgund 81', 'Monika', 'Romstar', 'White Success', 'Vivaldi', 'Black Velvet', 'Holstein Perle’. Various determinations and observations were carried out on cultivars based on an evaluation scale from 1 to 100 points, analyzing 13 different characters. The obtained results revealed after the evaluation, cultivars as `Monika`, `Romstar`, `Black Velvet` and `Burgund 81`obtained the highest score, over 85 points. These varieties are recommended for the future to be cultivated as cut flowers used in floral arrangements, but also for landscape design or genetic resources for breeding works.
