ROSE PLANT Filed March 24, 1955 United States Patent O ROSE PLANT Carl S. Shamburger, Tyler, Tex., assignor to C. W. Stuart & Co., Newark, N. Y., a corporation of New York Application March 24, 1955, Serial No. 496,627

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant which was discovered by me as a sport of the variety known as Cavalcade (Plant Patent No. 991) which I was growing on property under my direction and control near Tyler, Texas.

At the time of my discovery, I had a block of the variety Cavalcade under cultivation, and my attention was directed to one plant on which there appeared an unusual pink bloom which definitely was quite dilierent from the regular blooms of this variety. Continued observations and subsequent asexual reproduction of the pink sport by budding and also by cuttings, as made by me in the regular course of my commercial nursery operations near Tyler, Texas, showed that the unique characteristic of the pink sport came true to form and was established and transmitted through succeeding propagations.

My observations and tests further showed that the new variety has a distinct 2-tone effect of pink and silvery iridescent white, there being a contrast between the inside and the outside of the petals, as in the case of the parent variety, but the contrast being of entirely different colors as compared with those of the parent variety. In the bud stage, the color effect of my new variety is pink, with a light yellow diffusion. As the flower opens, the elfect is that of a deep pink' color, with a silvery color diffused with light yellow on the reverse of the petals, these colors changing to light silvery pink with a silvery white reverse as the flower matures. These color changes progress from day-to-day, and are definitely not color changes produced by fading. In all stages of the open flower, the flower has an entirely different appearance when viewed from above, as compared with that when viewed from the side.

Another distinction is found in the fragrance of the flowers of my new variety when compared with that of its parent and other hybrid polyantha roses. The flowers do not have the fruity fragrance of those of the parent variety, but instead, have a clear, sweet fragrance that is quite pronounced even at a substantial distance therefrom.

Except for the outstanding distinguishing characteristics noted above, the new variety has inherited most of the principal characteristics of its parent variety Cavalcade, and altogether, the characteristics and distinctions of the new variety definitely differentiate the same from its parent variety Cavalcade, as well as from all other varieties of which I am aware, and my tests and reproductions of the new variety have conclusively proved that the characteristics and distinctions are fully established and transmissible by asexual reproduction.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in difierent stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a general description of my new variety, with color terminology in accordance with the Horticultural Color Chart issued by the British Color Council in collaboration with the Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:
