No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A new variety of rose plant of the Floribunda class, being derived as a sport of the rose "Merko", and differing therefrom in its light pink coloration, as compared to the strong orange of the original stock. Flower size ranges from 3" to 4" when full blown.
