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 vigorous rose plant of the hybrid tea class, a sport from a rose plant entitled "Duchess" provides abundant long-lasting vibrant reddish-pink flowers which substantially maintain their true color from flower opening through petal drop on a continuous basis when grown in a greenhouse.
