ROSE PLANT Filed Sept. 10, 1954 United States Patent O ROSE PLANT Mathias Tantau, Uetersen, Holstein, Germany, assignor to Jackson & Perkins Company, Newark, N. Y., a corporation of New York Application September 10, 1954, Serial No. 455,372

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the large-flowered polyantha class, which was originated by me by crossing the variety Cinnabar (unpatented) With an unnamed and unpatented seedling of Cinnabar Kathe Duvigneau (unpatented).

The primary objective in making this cross was to produce a new variety of rose which combines the brilliant coloring of the flowers of the variety Cinnabar with a better and taller-growing plant habit, the latter characteristic being one of the features of the more vigorous seedling parent which normally produces rather poor flowers. This objective was fully achieved, as evidenced by the fact that my new variety is particularly characterized by its upright and vigorous growth of medium height, a free production of flower clusters which are relatively long-lasting on the plant, and the distinctively different color of the flowers, said color being Scarlet Red in the bud stage, changing to Rose Doree, lightly overcast with Scarlet Red, in the fully open flowers.

Asexual reproduction of my new variety by budding at Newark, New York, U. S. A., and at Pleasanton, California, U. S. A., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the flowers, stems and foliage of my new variety in different 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.
