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
There is disclosed an azalea plant having flower and growth habit similarity to a known variety Azalea kaempferi "Fedora" an unpatented variety, and foliage characteristics of a Kurume Azalea Hinodegiri, also an unpatented variety, distinguished however by the abundant flowers of purplish pink color with a pronounced white stripe on the reverse of each petal extending from the base at the center thereof to the extremity, the glossy, dark green foliage which is retained well in winter, and the upright habit of growth which makes it stand out among other low growing varieties.
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 azalea plant, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of purplish pink flowers borne in abundance in irregular rounded clusters on strong stems, the reverse of each flower petal having a nearly white stripe extending from the base at the center thereof, the evergreen, glossy dark green foliage retained well in winter, and the tall upright habit.
