ROSE PLANT Filed May 10, 1974 United States Patent I Plant Pat. 3,749 Patented July 29, 1975' 3,749 ROSE PLANT Roy L. Byrum, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind. Filed May 10, 1974, Ser. No. 468,893 Int. Cl. A01h 5/00 US. Cl. Plt.18 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of hybrid tea rose intended for greenhouse culture, distinguished by its continuous and abundant production of soft pink flowers of medium size borne on strong upright stems of medium length, particularly suited for the commercial trade because of their color compatibility in arrangements with allied flowers, the very attractive and unusual shape of the bud, and the longevity of the blooms as cut flowers.

BACKGROUND OF THE INVENTION This new variety of rose plant originated as a-seedling of Eternal Sun (P.P. 2,689) X Carina (P.P. 2,378), the crossing having been made by me at Richmond, Ind., in March 1966 in the course of breeding efforts being carried on by me with the object of developing new and improved rose varieties for the greenhouse production of cut flowers. This plant was discovered by me in October 1967 and was selected for propagation and test because of the lovely blush pink color of its beautifully formed flower and subsequent propagation of this plant by budding at Hamilton City, Calif., under my direction and through many generations has demonstrated that its novel color characteristic as well as other morphological and physiological advantages hereinafter described are firmly fixed and hold true from generation to generation.

DESCRIPTION OF THE DRAWING My new rose plant is illustrated by the accompanying photographic drawing, in full color, which shows the buds in progressive stages of development, a face view of a fully opened flower, and the characteristics of the wood and the foliage, the colors of the buds and blossom being as nearly true as it is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT The following is a detailed description of this new variety of rose plant with color designations according to Robert Wilsons Horticultural Colour Chart (W) published by the Royal Horticultural Society of London, England, and according to Kosters Color Guide (K), all observations having been made at Richmond, Ind., where this new rose plant is grown in greenhouse.

This new rose plant variety is completely different and is much better in color than its seed parent in that it is of a soft pleasing blush pink and better adapted to the commercial trade, whereas the seed parent is more novel in nature. The new plant is an improvement over its pollen parent in that its flowers are borne on stronger upright stems and are larger in size, especially in hot weather, and the plant does not slow down in winter months. In addition to the free growing habits of this new plant, the predominate distinctive features reside in the unusual shape of the bud, as shown in the drawing, the soft pink coloration of the flower, and its 5 to 6 day vase life as a cut flower.

The claim:

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by the soft pink color of the flowers and its free growing habits which provide a continuous and abundant year around production of blooms borne on strong erect stems.
