No cultivar name of record
This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.
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
This invention relates to a new and distinct variety of Belgian-Indica type Azalea named Lucille K which is a sport of Azalea U.S. Plant Pat. No. 1,159 named Red Wing. Lucille K is like its parent Red Wing in many of its vegetative characteristics, but is distinctly different from Red Wing in the following ways: Flower color, flower petal always has a pronounced white margin, the flowers are hardier resulting in longer blooming, and the plant flowers naturally on or about Valentine's Day (February 14th).
