ROSE PLANT Filed Jan. 17, 1946 Patented Dec. 10, 1946 UNITED Plant Pat. 71 6 STATES PATENT OFFICE ROSE PLANT Application January 17, 1946, Serial No. 641,666

1 Claim. 1

The present invention relates to a new and distinct variety of hybrid tea rose plant, resulting from a definite effort to produce a rose which would combine the best characteristics of two well-known varieties, Mrs. Sam McGredy and President Herbert Hoover, while eliminating some of the undesirable characteristics of the individual parents.

Inorder to best appreciate the distinguishing features of this new rose, a comparison of the same with each of the parents will now be made.

The variety Mrs. Sam McGredy, the seed parent, has a strong and pleasing flower color in salmon-orange and pink shades. These new ers are borne on a plant with handsome, glossy foliage which is weak and spreading and has also a tendency to produce willowy-growth.

The variety President Herbert Hoover is characterized by extremely vigorous, upright growth, with long, strong stems, but with foliage dull in appearance and quite susceptible to mildew. Its flowers are not strongly colored and are often characterized by the presence of an objectionable blue pigment in the outer extremities of the flower and with a pale, quick-fading center.

This new variety is a combination of the dominant characteristics of both parents, that is, the strongly colored flower of the seed parent and the habit and vigor of growth of the pollen parent. In other respects, the petals of the new rose have more substance, and the flowers more fragrance, said flowers being borne on stronger and longer stems than those of Mrs. Sam Mc- Gredy. The foliage is glossy and resistant to mildew. This foliage on new growth has a predominating shade of red, as hereinafter set forth specifically, more nearly typical of Mrs. Sam McGredy, but slightly darker, and both new and mature foliage are heavier and larger than that of either parent.

Further, this new rose has a greater freedom of bloom than either of its parents, as well as a more attractive shape in the loud. The length of bud is comparable to that of the pollen parent, but the form is more graceful because of the typical urn-shape as compared with the somewhat stiff pointed bud of said parent. The bud, furthermore, is longer than that of the seed parent and more gracefully shaped because of its urn-shape characteristic. It is further characterized by fluted or ruflled edges of the petals which are quite pronounced in the bud.

Perhaps the most predominant characteristic of this new rose is found in the novel color combination of its flowers running from chrome yellow at the base, gradually shading into other colors progressing towards the outer circumference through shades of rose, pink, madder, carmine, begonia and others as shown in the accompanying drawing as nearly as possible to depict in detail.

Because of the combination of all these characteristics in this new variety, it is easily and importantly distinguishable from any other va riety now known in commerce.

In the accompanying drawing are shown specimens of the new variety in the different stages of development of the flower from bud to fully open bloom, together with new and mature foliage.

AseXual reproduction shows that the charac" teristics hold true through succeeding propagations.

The following is a detailed description of the new variety, all reference to color being in accordance with the R. F. Wilsons Horticultural Colour Chart, except where indicated to be in accordance with Ridgways Color Standard and Nomenclature:
