ROSE PLANT Filed June 1, 1970 //Vl/E N TOR. ROY L. BYRUM United States Patent 3,126 ROSE PLANT Roy L. Byrum, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind. Filed June 1, 1970, Ser. No. 42,610 Int. Cl. A01h /00 U.S. Cl. Plt.18 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of hybrid tea rose suitable for year around greenhouse forcing and distinguished by its continuous free production of large sized blooms having excellent petal texture, a pleasing coloration, extending from French Rose to Porcelain Rose, unusually strong and long stems, and a vigorous growth habit.

BACKGROUND OF THE INVENTION This new variety of rose plant was produced by me by crossing Eternal Sun (RP. 2,689), as the seed parent, with Carina (P.P. 2,378) with the object of developing a tea rose plant having the production and keeping qualities of Carina and the vigorous and strong growth habit of Eternal Sun for use as a greenhouse forcing variety that would not be adversely affected by lack of sunlight during the winter growing season. This plant resulted as a seedling from a crossing made by me in March 1966 at Richmond, Ind., and, upon its blooming in the spring of 1967, was observed to have much of the desirable characteristics I was seeking.

Asexual propagation of this new plant by rooting at Richmond, Ind., and by budding at Hamilton City, Calif., through succeeding generations at each place, has shown that all of the sought for characteristics for an improved greenhouse forcing variety of hybrid tea rose have been obtained and that these characteristics are fixed and hold true from generation to generation.

DESCRIPTION OF THE DRAWING This new variety of rose plant is illustrated by the accompanying full color drawing showing the form of the opened flower and the buds and showing specimens of foliage and old and young wood.

DESCRIPTION OF THE PLANT The following is a detailed description of my new variety of rose plant with specifications of color according to Kosters Color Guide, indicated by (K), and Robert S. Wilson Horticultural Chart, indicated by (W). All observations were made from plants and cut flowers grown in greenhouse in Richmond, Ind.

The following are observations of a greenhouse grown flower newly opened in September 1969 at Richmond, Ind.

The following observations were made of a rose opened for three days in a greenhouse in November 1969 at Richmond, Ind.:

Stigmas: Color-Crearny White (K) #2. Ovaries: Some protruding from calyx.

My new variety of tea rose is considered to be better than its seed parent because it has a larger bloom and much better keeping qualities. Likewise the new variety is an improvement over its pollen parent because it has a more pleasing color, stronger stems, and is not adversely affected by the lack of light during winter months. All in all, my new variety of tea rose is considered to be a superior greenhouse forcing variety.

I claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by its pleasing French Rose to Porcelain Rose range of coloration, its free and continuous production of very large blooms with unusually strong stems, and its good growth and production for year around greenhouse forcing.
