ROSE PLANT Filed March 9, 1965 United States Patent 2,626 ROSE PLANT Roy L. Byrum, Richmond, Kath, assignor to Joseph H. Hill Company, Richmond, End, a corporation of Indiana Filed Mar. 9, 1965, Ser. No. 438,439 1 Claim. (Cl. Pit-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 derived from a cross of another unnamed and unpatented seedling Garnette Supreme (Plant Patent No. 1,318) with the variety Rumba (Plant Patent No. 1,919).

The primary objective of this breeding was to produce a new and improved variety of rose plant having the good foliage and the good flower keeping qualities of the pollen parent Rumba, but characterized by better flower production when grown in greenhouses during winter months. This objective was fully achieved, along with other desirable improvements, as evidenced by the following characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(1) Abundant, medium size and attractive foliage;

(2) Good flower keeping qualities;

(3) Good flower production when grown in greenhouses during winter months; and

(4) An unusual range of flower colors beginning as a deep Orange Yellow color in the bud stage and then progressing through lighter shades of yellow to various shades of pink at maturity.

The unnamed seed parent of my new variety was a red flowered floribunda type having the characteristic of vigorous growth.- The new variety is considered to be an improvement over this parent variety because it combines the vigorous growth characteristic of the seed parent with an unusual flower color range.

As compared with its pollen parent Rumba, the new variety achieves better flower production in greenhouses, especially during the winter months, and it also produces larger and more colorful flowers which are borne on longer stems and are therefore more suitable for out flower purposes.

Asexual reproduction of my new variety by grafting, as performed at Richmond, Indiana, and also by budding, as performed at Wills Point, Texas, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers 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.

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:

Type: Bush; seedling. Class: Floribunda. Breeding: Seedling.

Seed parent.An unnamed red flowered floribunda seedling. Pollen parent-Rumba. Propagation: Holds its distinguishing characteristics through succeeding propagations by both budding and grafting.
