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 hardy rose plant of the hybrid miniature class, having a vigorous growth habit, and having slightly better than average resistance to mildew, said plant producing, throughout the growing season, a profusion of well-formed buds and flowers, these latter being from about 1 inch to 11/4 inches in size and having from 22 to 28 petals plus 2 to 6 petaloids. The overall color effect of the flowers is rather uniformly coral and pink. The flowers are sterile, and do not generally set hips.
