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 flowering cherry tree selected as a seedling in a block of open pollinated variety Prunus yedoensis "Akebono", (unpatented) distinguished from "Akebono" by the strong pink color of its abundant flowers when fully open, "Akebono" flowers being pale pink by comparison, the variety hereof being vigorous with spreading growth broader than tall, the flower buds being resistant to freezing, blooming abundantly when regular "Akebono" trees lost as much as ninety percent of buds due to freezing, and the bark showing no injury to minus 19 degrees F.

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 flowering cherry tree substantially as herein shown and described, characterized particularly as to novelty by the unique combination of the strong pink color of its abundant flowers, vigorous, spreading, broader than tall habit, rapid growth, resistance to cold damage to buds, withstanding temperatures to minus nineteen degrees F., in contrast to other usual Prunus yedoensis trees which suffer bud damage such as to lose ninety percent of their buds and bark injury from freezing.
