United States Patent O 3,651 ROSE PLANT William A. Warriner, Tustin, Califi, assignor to Jackson & Perkins Company, Medford, Oreg. Filed Sept. 7, 1973, Ser. No. 395,248 Int. Cl. A01h 5/00 U.S. Cl. Plt.24 1 Claim This present invention relates to a new cultivar registered with the International Registration Authority for Roses, Columbus, Ohio, as Sunstrike, rose plant of the fioribunda class which was originated by me by crossing the cultivar Spanish Sun, U.S. Plant Patent 2,809, with pollen from an unnamed seedling cultivar, resulting from a cross of the cultivar Buccaneer, U.S. Plant Patent 1,119 with the cultivar Zorina, Plant Patent 2,321.

The primary objective of this breeding was to produce a new yellow fioribunda suitable for greenhouse forcing, similar to the cultivar Spanish Sun, but with a longer lasting, nonfading color. This objective was substantially achieved as evidenced by the following unique combination of characteristics which are outstanding in the new cultivar and which distinguish it from its parents as well as from all other cultivars of which I am aware.

1. A vigorous, well branched plant, very similar to Spanish Sun in habit.

2. Buds of approximately the same length as Spanish Sun but more double, usually having 40-50 petals while Spanish Sun has normally 30-40 petals.

3. Color in the bud stage is Buttercup yellow and rarely showing a fading of the outer petals as often seen in Spanish Sun and Golden Garnette.

4. As cut flowers, the color of this new cultivar holds intensity longer than Spanish Sun and Golden Garnette.

5. Fragrance of this new cultivar is quite similar to the fragrance of licorice and very unlike the fragrance of Spanish Sun.

Asexual reproduction of this new cultivar by budding, as performed at Wasco, California, 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 vegetative growth and flowers of this new cultivar in different stages of development depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose variety with color terminology in accordance with Wilsons Horticultural Color Chart, except where ordinary dictionary significance of color is indicated.
