Naming a rose is a complex operation that can take 2 - 7 years. If you haven't hybridized your own rose, you will need to find a rose breeder who has a suitable unnamed new variety that has been tested and is ready to register. Then, you need to either persuade or pay them to name the rose as you wish. Once the rose is registered, there is still no assurance that it will be brought into commerce and become a successful variety. See the article A Rose for the Games .
Written permission has to be given in order to name a rose after a living person.
You'll find the Societies' addresses under Clubs and Associations in EveryRose. These rose hybrids are not often suitable for garden growing, and relatively few of them are available to purchase. There are only a a few, such as Bridal White, Antique Silk, Kardinal and Aalsmeer Gold which are both garden and florists roses. As a group, they are generally fragrant, thorny, with dark green foliage, bloom once in the summer, and can be susceptible to mildew. They are unruly in growth and appreciate training or support, but with good weather and some care they can provide a spectacular, heavily scented display of old-fashioned rose blooms.
