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
A new hybrid tea rose of the tall bush type, tender to half-hardy, raised as an outdoor seedling and useful primarily for garden decoration. One notable characteristic is the uniform medium golden yellow blooms, which are of large size (13 to 14 centimeters) and fragrant, with 25 to 34 petals plus 2 to 4 petaloids. The color lightens as the flower matures. The plant is vigorous and blooms abundantly.
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 hybrid tea rose, substantially as described and illustrated herein, said plant being characterized by a very vigorous upright-spreading to semi-climbing habit, which grows tall and bushy and has foliage of a medium olive-green color with leaflets tending to be somewhat folded inward bilaterally from the midrib, yet hanging downward from the rachis, the flowering of said plant being characterized in that its sepals turn down quickly as the bud begins to open, the blooms have double petalage of from about 25 to 34 petals with two to four petaloids; and the bloom spreads from 5 to 51/2 inches, producing an overall color effect at first of a medium golden yellow, without significant other coloration, which lightens in shade as the bloom matures.
