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 heavily branched, bushy rose plant of the miniature class, characterized particularly by its abundance and continuity of blooms, leaflets of a long oval shape, its strong resistance to rose powdery mildew, with little or no fragrance.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of rose of the miniature class, substantially as herein illustrated and described, characterized particularly as to novelty by the unique combination of its vigorous well-branched habit of growth, its long oval leaflets which are resistant to rose powdery mildew, its abundant continuous production of light yellow buds which age to white and are nearly scentless.
