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 hardy variety of hybrid grandiflora rose plant, of the outdoor, bush type, having a strong citrus fragrance and blooming abundantly almost throughout the growing season. Blooms are borne sometimes singly but usually three to five on a stem, and display color effects predominantly of off-white, suffusing to yellow-green. Flowers range from 3 to 31/2 inches across, with from 25 to 30 petals, plus 0 to 5 petaloids.
