ROSE PLANT Filed Sept. 9, 1970 WILLIAM A. WARRINER INVENTOR BUOKHORN, BLORE, KLARQUIST & SPARKMAN ATTORNEYS United States Patent 3,144 ROSE PLANT William A. Warriner, Tustin, Califi, assignor to Jackson & Perkins Company, Medford, Oreg. Filed Sept. 9, 1970, Ser. No. 70,943 Int. Cl. A01h /00 US. Cl. Plt.-28 1 Claim The present invention relates to a new and distinct variety of rose plant of the floribunda class originated by crossing two unnamed seedlings.

The primary objective of this breeding was to produce a new and improved variety of the floribunda class hearing long lasting, non-blueing, well formed red flowers in quantities suitable for greenhouse production of cut blooms.

This objective was fully achieved, along with other desirable improvements 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) A vigorous and angular branching habit of growth.

(2) An unusually pronounced resistance to elTects of rose powdery mildew as observed under greenhouse and garden conditions at Irvine, Calif.

(3) A unique persistence in flower color, showing very little change, after several days, from Currant Red (Wilson).

(4) Stifl, strong flower petals lasting on the flower for 7 to 10 days under normal, comfortable living conditions.

Asexual reproduction of my new variety by budding, as performed at Wasco, Calif, shows that the aforementioned characteristics and distinctions propagate true to form through succeeding propagation.

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

The following is a detailed description of my new variety, with color terminology in accordance with either Ridgways Color Standards and Nomenclature (R), or Wilsons Horticultural Color Chart (W), except where ordinary dictionary significance of color is indicated.

I claim; v. v I

1. A new and distinct variety of rose plant of the floribunda class substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a vigorous, angularly branched habit of growth, an ovoid, pointed bud of maroon color, a uniformly imbricated flower form, the color of the open flower is Currant Red on the upper side of the petals and Cardinal Red on the reverse side, and an unusually pronounced resistance to powdery mildew, wherever this varity has been observed, is also a distinguishing characteristic.
