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 and distinct bi-colored rose plant for greenhouse culture and cut flower production, distinguished by the Talisman coloration of its medium sized blooms which is intense and brilliant both in the bud stage and as an open flower, and by its above average vase life and keeping qualities as a cut flower. This rose plant has a vigorous growth habit with a continuous and abundant production of flowers, borne singly on stems of medium length, and an abundance of dark green, glossy foliage.
