ROSE PLANT Filed March 15, 1966 United States Patent 2,728 ROSE PLANT Roy L. Byrnrn, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind., a corporation of Indiana Filed Mar. 15, 1966, Ser. No. 534,540 1 Claim. (Cl. Plt.--22) The present invention relates to a new and distinct variety of rose plant of the fioribunda class, which was originated by me by crossing an unnamed and unpatented seedling of unidentified parentage, but identified in my breeding records as #58Q, with the variety known as Rumba (Plant Patent No. 1,919).

The primary objective of this breeding was to produce a new rose variety which combines the good flower production and orange flower color of the unnamed seed parent with the stronger stems, excellent foliage and good flower keeping qualities of the pollen parent, Rumba. This objective was fully achieved, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other rose varieties of which I am aware:

(I) Abundant dark green glossy foliage which enhances and intensifies the flower color;

(2) Long and upright flower stems, with very few disbuds;

(3) Abundant production of flowers of bright orange general color tonality which is unusual in the class of greenhouse forcing rose varieties; and

(4) Excellent keeping qualities of the flowers as cut flowers.

In comparison with its unnamed seed parent, which bears flowers of orange color and has very good growing habits except for weak flower stems, my new variety has retained these qualities with substantial improvement in the stems which are strong and straight.

As compared with its pollen parent, Rumba, the new variety is better for greenhouse forcing, and produces larger blooms of more uniform color and on longer stems.

Asexual reproduction of my variety by grafting, as performed at Richmond, Ind, and also by budding, as performed at Livermore, Calif., shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. Q

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in diflerent 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 detailed description of the new variety, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as (W)), and Kosters Color Guide (hereinafter abbreviated as (K)), except where general color terms of ordinary dictionary significance are obvious:
